MCP651/1S/2/3/4/5/9 50 MHz, 200 µV Op Amps with mCal Features: Description: • • • • • • The Microchip Technology Inc. MCP651/1S/2/3/4/5/9 family of high bandwidth and high slew rate operational amplifiers features low offset. At power-up, these op amps are self-calibrated using mCal. Some package options also provide a Calibration/Chip Select pin (CAL/CS) that supports a Low-Power mode of operation, with offset calibration at the time normal operation is re-started. These amplifiers are optimized for high speed, low noise and distortion, single-supply operation with rail-to-rail output and an input that includes the negative rail. • • • • • • Gain-Bandwidth Product: 50 MHz Slew Rate: 30 V/µs Low Input Offset: ±200 µV (maximum) Low Input Bias Current: 6 pA (typical) Noise: 7.5 nV/Hz, at 1 MHz Ease-of-Use: - Unity-Gain Stable - Rail-to-Rail Output - Input Range incl.

This time ensures that the internal logic recognizes the edge. However, for the rising edge case, if CAL/CS is raised before the calibration is complete, the calibration will be aborted and the part will return to Low-Power mode. For the MCP655 dual, there is an additional constraint. CALA/CSA and CALB/CSB can be toggled simultaneously (within a time much smaller than tCSU) to make both op amps perform the same function simultaneously. If they are toggled independently, then CALA/CSA (CALB/CSB) cannot be allowed to toggle while op amp B (op amp A) is in Calibration mode; allow more than the maximum tCON time (4 ms) before the other side is toggled. For the MCP659 quad, there is an additional constraint. CALAD/CSAD and CALBC/CSBC can be toggled simultaneously (within a time much smaller than tCSU) to make all four op amps perform the same function simultaneously, and the maximum tCON time is approximately doubled (8 ms). If they are toggled independently, then CALAD/CSAD (CALBC/CSBC) cannot be allowed to toggle while op amps B and C (op amps A and D) are in Calibration mode; allow more than the maximum tCON time (8 ms) before the other side is toggled. 2009-2014 Microchip Technology Inc.

MCP651/1S/2/3/4/5/9 3.1 Analog Outputs The analog output pins (VOUT) are low-impedance voltage sources. 3.2 Analog Inputs The non-inverting and inverting inputs (VIN+, VIN–, …) are high-impedance CMOS inputs with low bias currents. 3.3 Power Supply Pins The positive power supply (VDD) is 2.5V to 5.5V higher than the negative power supply (VSS). For normal operation, the other pins are between VSS and VDD. Typically, these parts are used in a single (positive) supply configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need bypass capacitors. 3.4 Calibration Common Mode Voltage Input A low-impedance voltage placed at this input (VCAL) will set the op amps’ Common mode input voltage during calibration. If this pin is left open, the Common mode input voltage during calibration is approximately VDD/3. The internal resistor divider is disconnected from the supplies whenever the part is not in calibration. 2009-2014 Microchip Technology Inc. 3.5 Calibrate/Chip Select Digital Input This input (CAL/CS, …) is a CMOS, Schmitt-Triggered input that affects the Calibration and Low-Power modes of operation. When this pin goes high, the part is placed into a Low-Power mode and the output is High Z. When this pin goes low, a calibration sequence is started (which corrects VOS). At the end of the calibration sequence, the output becomes low-impedance and the part resumes normal operation. An internal POR triggers a calibration event when the part is powered on, or when the supply voltage drops too low. Thus, the MCP652 parts are calibrated, even though they do not have a CAL/CS pin. 3.6 Exposed Thermal Pad (EP) There is an internal connection between the Exposed Thermal Pad (EP) and the VSS pin; they must be connected to the same potential on the Printed Circuit Board (PCB). This pad can be connected to a PCB ground plane to provide a larger heat sink. This improves the package thermal resistance (JA). DS20002146D-page 21 MCP651/1S/2/3/4/5/9 4.0 APPLICATIONS The MCP651/1S/2/3/4/5/9 family of self-zeroed op amps is manufactured using Microchip’s state-of-theart CMOS process. It is designed for low-cost, lowpower and high-precision applications. Its low supply voltage, low quiescent current and wide bandwidth makes the MCP651/1S/2/3/4/5/9 ideal for batterypowered applications. 4.1 Calibration and Chip Select These op amps include circuitry for dynamic calibration of the offset voltage (VOS). 4.1.1 mCal CALIBRATION CIRCUITRY The internal mCal circuitry, when activated, starts a delay timer (to wait for the op amp to settle to its new bias point), then calibrates the input offset voltage (VOS). The mCal circuitry is triggered at power-up (and after some power brown-out events) by the internal POR, and by the memory’s Parity Detector. The powerup time, when the mCal circuitry triggers the calibration sequence, is 200 ms (typical). 4.1.2 CAL/CS PIN The CAL/CS pin gives the user a means to externally demand a Low-Power mode of operation, then to calibrate VOS. Using the CAL/CS pin makes it possible to correct VOS as it drifts over time (1/f noise and aging; see Figure 2-35) and across temperature. The CAL/CS pin performs two functions: it places the op amp(s) in a Low-Power mode when it is held high, and starts a calibration event (correction of VOS) after a rising edge. While in the Low-Power mode, the quiescent current is quite small (ISS = -3 µA, typical). The output is also in a High Z state. During the calibration event, the quiescent current is near, but smaller than, the specified quiescent current (6 mA, typical). The output continues in the High Z state, and the inputs are disconnected from the external circuit, to prevent internal signals from affecting circuit operation. The op amp inputs are internally connected to a Common mode voltage buffer and feedback resistors. The offset is corrected (using a digital state machine, logic and memory), and the calibration constants are stored in memory. Once the calibration event is completed, the amplifier is reconnected to the external circuitry. The turn-on time, when calibration is started with the CAL/CS pin, is 3 ms (typical). There is an internal 5 M pull-down resistor tied to the CAL/CS pin. If the CAL/CS pin is left floating, the amplifier operates normally. For the MCP655 dual and the MCP659 quad, there is an additional constraint on toggling the two CAL/CS pins close together; see the tCON specification in Table 1-3. If the two pins are toggled simultaneously, or if they are toggled separately with an adequate delay between them (greater than tCON), then the CAL/CS inputs are accepted as valid. If one of the two pins toggles while the other pin’s calibration routine is in progress, then an invalid input occurs and the result is unpredictable. 4.1.3 INTERNAL POR This part includes an internal Power-On Reset (POR) to protect the internal calibration memory cells. The POR monitors the power supply voltage (VDD). When the POR detects a low VDD event, it places the part into the Low-Power mode of operation. When the POR detects a normal VDD event, it starts a delay counter, then triggers an calibration event. The additional delay gives a total POR turn-on time of 200 ms (typical); this is also the power-up time (since the POR is triggered at power-up). 4.1.4 PARITY DETECTOR A parity error detector monitors the memory contents for any corruption. In the rare event that a parity error is detected (e.g., corruption from an alpha particle), a POR event is automatically triggered. This will cause the input offset voltage to be re-corrected, and the op amp will not return to normal operation for a period of time (the POR turn-on time, tPON). 4.1.5 CALIBRATION INPUT PIN A VCAL pin is available in some options (e.g., the single MCP651) for those applications that need the calibration to occur at an internally driven Common mode voltage other than VDD/3. Figure 4-1 shows the reference circuit that internally sets the op amp’s Common mode reference voltage (VCM_INT) during calibration (the resistors are disconnected from the supplies at other times). The 5 k resistor provides over-current protection for the buffer. 300 k VCM_INT 5 k VCAL BUFFER 150 k VSS FIGURE 4-1: Input Circuitry.

MCP651/1S/2/3/4/5/9 When the VCAL pin is left open, the internal resistor divider generates a VCM_INT of approximately VDD/3, which is near the center of the input Common mode voltage range. It is recommended that an external capacitor from VCAL to ground be added to improve noise immunity. When the VCAL pin is driven by an external voltage source, which is within its specified range, the op amp will have its input offset voltage calibrated at that Common mode input voltage. Make sure that VCAL is within its specified range. It is possible to use an external resistor voltage divider to modify VCM_INT; see Figure 4-2. The internal circuitry at the VCAL pin looks like 100 k tied to VDD/3. The parallel equivalent of R1 and R2 should be much smaller than 100 k to minimize differences in matching and temperature drift between the internal and external resistors. Again, make sure that VCAL is within its specified range.

Figure 2-41 shows an input voltage exceeding both supplies with no phase inversion. 4.2.2 VDD Bond Pad VIN+ Bond Pad INPUT VOLTAGE AND CURRENT LIMITS The ESD protection on the inputs can be depicted as shown in Figure 4-3. This structure was chosen to protect the input transistors, and to minimize input bias current (IB). The input ESD diodes clamp the inputs when they try to go more than one diode drop below VSS. They also clamp any voltages that go too far 2009-2014 Microchip Technology Inc. Bond VIN– Pad Input Stage VSS Bond Pad FIGURE 4-3: Structures. Simplified Analog Input ESD In order to prevent damage and/or improper operation of these amplifiers, the circuit must limit the currents (and voltages) at the input pins (see Section 1.1 “Absolute Maximum Ratings †”). Figure 4-4 shows the recommended approach to protecting these inputs. The internal ESD diodes prevent the input pins (VIN+ and VIN–) from going too far below ground, and the resistors R1 and R2 limit the possible current drawn out of the input pins. Diodes D1 and D2 prevent the input pins (VIN+ and VIN–) from going too far above VDD, and dump any currents onto VDD. When implemented as shown, resistors R1 and R2 also limit the current through D1 and D2. Setting VCM with External For instance, a design goal to set VCM_INT = 0.1V when VDD = 2.5V could be met with: R1 = 24.3 k, R2 = 1.00 k and C1 = 100 nF. This will keep VCAL within its range for any VDD, and should be close enough to 0V for ground-based applications. 4.2 above VDD; their breakdown voltage is high enough to allow normal operation, and low enough to bypass quick ESD events within the specified limits.

Protecting the Analog It is also possible to connect the diodes to the left of the resistor R1 and R2. In this case, the currents through the diodes D1 and D2 need to be limited by some other mechanism. The resistors then serve as in-rush current limiters; the DC current into the input pins (VIN+ and VIN–) should be very small. DS20002146D-page 23 When operating at very low non-inverting gains, the output voltage is limited at the top by the VCM range (< VDD – 1.3V); see Figure 4-5. +I SC Limited RL = 100Ω RL = 10Ω FIGURE 4-6: 120 100 80 60 40 0 20 -20 -40 -60 VOL Limited -80 The input stage of the MCP651/1S/2/3/4/5/9 op amps uses a differential PMOS input stage. It operates at low Common mode input voltage (VCM), with VCM up to VDD – 1.3V and down to VSS – 0.3V. The input offset voltage (VOS) is measured at VCM = VSS – 0.3V and VDD – 1.3V to ensure proper operation. See Figure 2-6 and Figure 2-7 for temperature effects.

For instance, the output voltage swings to within 15 mV of the negative rail with a 1 k load tied to VDD/2. 4.3.0.2 Output Current Figure 4-6 shows the possible combinations of output voltage (VOUT) and output current (IOUT). IOUT is positive when it flows out of the op amp into the external circuit. DS20002146D-page 24 2009-2014 Microchip Technology Inc. MCP651/1S/2/3/4/5/9 4.3.0.3 Power Dissipation Since the output short circuit current (ISC) is specified at ±100 mA (typical), these op amps are capable of both delivering and dissipating significant power. Two common loads, and their impact on the op amp’s power dissipation, will be discussed. Figure 4-7 shows a capacitive load (CL), which is driven by a sine wave with DC offset. The capacitive load causes the op amp to output higher currents at higher frequencies. Because the output rectifies IOUT, the op amp’s dissipated power increases (even though the capacitor does not dissipate power). Figure 4-7 shows a resistive load (RL) with a DC output voltage (VOUT). VL is RL’s ground point, VSS is usually ground (0V) and IOUT is the output current. The input currents are assumed to be negligible. VDD IDD IOUT VOUT MCP65X VDD IDD CL ISS IOUT VSS VOUT MCP65X RL ISS FIGURE 4-8: Diagram for Capacitive Load Power Calculations.

The bandwidth will be generally lower than the bandwidth with no capacitive load. The maximum ambient to junction temperature rise (TJA) and junction temperature (TJ) can be calculated using the maximum expected package power (PPKG), ambient temperature (TA) and the package thermal resistance (JA) found in Table 1-4: EQUATION 4-8: T JA = PPKG JA T J = T A + T JA The worst-case power de-rating for the op amps in a particular package can be easily calculated: EQUATION 4-9: RG VOUT RN TA = Ambient temperature (°C) Several techniques are available to reduce TJA for a given package: • Reduce JA - Use another package - Improve the PCB layout (ground plane, etc.) - Add heat sinks and air flow • Reduce max(PPKG) - Increase RL - Decrease CL - Limit IOUT using RISO (see Figure 4-9) - Decrease VDD 4.4 4.4.1 Improving Stability CAPACITIVE LOADS Driving large capacitive loads can cause stability problems for voltage feedback op amps. As the load capacitance increases, the feedback loop’s phase margin decreases and the closed-loop bandwidth is reduced. This produces gain peaking in the frequency response, with overshoot and ringing in the step response. See Figure 2-30. A unity-gain buffer (G = +1) is the most sensitive to capacitive loads, though all gains show the same general behavior. DS20002146D-page 26 MCP65X FIGURE 4-9: Output Resistor, RISO Stabilizes Large Capacitive Loads. Figure 4-10 gives recommended RISO values for different capacitive loads and gains. The x-axis is the normalized load capacitance (CL/GN), where GN is the circuit’s noise gain. For non-inverting gains, GN and the Signal Gain are equal. For inverting gains, GN is 1+|Signal Gain| (e.g., -1 V/V gives GN = +2 V/V). 100 Recommended R ISO (Ω) TJmax = Absolute maximum junction temperature (°C) RISO CL T Jmax – T A P PKG ------------------------- JA Where: RF 10 GN = +1 GN +2 1 10p 1.E-11 100p 1n 1.E-10 1.E-09 Normalized Capacitance; CL/GN (F) 10n 1.E-08 FIGURE 4-10: Recommended RISO Values for Capacitive Loads. After selecting RISO for your circuit, double check the resulting frequency response peaking and step response overshoot. Modify RISO’s value until the response is reasonable. Bench evaluation and simulations with the MCP651/1S/2/3/4/5/9 SPICE macro model are helpful. 4.4.2 GAIN PEAKING Figure 4-11 shows an op amp circuit that represents non-inverting amplifiers (VM is a DC voltage and VP is the input) or inverting amplifiers (VP is a DC voltage and VM is the input). The capacitances CN and CG represent the total capacitance at the input pins; they include the op amp’s Common mode input capacitance (CCM), board parasitic capacitance and any capacitor placed in parallel. 2009-2014 Microchip Technology Inc.

CG also reduces the phase margin of the feedback loop, which becomes less stable. This effect can be reduced by either reducing CG or RF. CN and RN form a low-pass filter that affects the signal at VP. This filter has a single real pole at 1/(2RNCN). The largest value of RF that should be used depends on noise gain (see GN in Section 4.4.1 “Capacitive Loads”) and CG. Figure 4-12 shows the maximum recommended RF for several CG values. Maximum Recommended RF (Ω) 1.E+05 100k 4.5 Power Supply With this family of operational amplifiers, the Power Supply pin (VDD for single supply) should have a local bypass capacitor (i.e., 0.01 µF to 0.1 µF) within 2 mm for good high-frequency performance. Surface mount, multilayer ceramic capacitors, or their equivalent, should be used. These op amps require a bulk capacitor (i.e., 2.2 µF or larger) within 50 mm to provide large, slow currents. Tantalum capacitors, or their equivalent, may be a good choice. This bulk capacitor can be shared with other nearby analog parts as long as crosstalk through the supplies does not prove to be a problem.

The unitygain buffer usually has RF = 0 and RG open. Figure 2-39 and Figure 2-40 show the small signal and large signal step responses at G = -1 V/V. Since the noise gain is 2 V/V and CG 10 pF, the resistors were chosen to be RF = RG = 499 and RN = 249. It is also possible to add a capacitor (CF) in parallel with RF to compensate for the de-stabilizing effect of CG. This makes it possible to use larger values of RF. The conditions for stability are summarized in Equation 410. 2009-2014 Microchip Technology Inc. High-Speed PCB Layout These op amps are fast enough that a little extra care in the PCB (Printed Circuit Board) layout can make a significant difference in performance. Good PCB layout techniques will help achieve the performance shown in the specifications and Typical Performance Curves; it will also help minimize EMC (Electro-Magnetic Compatibility) issues. Use a solid ground plane. Connect the bypass local capacitor(s) to this plane with minimal length traces to cut down inductive and capacitive crosstalk. Separate digital from analog, low-speed from highspeed, and low-power from high-power. This will reduce interference. Keep sensitive traces short and straight. Separate them from interfering components and traces. This is especially important for high-frequency (low rise time) signals. Sometimes, it helps to place guard traces next to victim traces. They should be on both sides of the victim trace, and as close as possible. Connect guard traces to ground plane at both ends, and in the middle for long traces. Use coax cables, or low inductance wiring, to route signal and power to and from the PCB. Mutual and self inductance of power wires is often a cause of crosstalk and unusual behavior.

Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
