For normal operation, the other pins are at voltages between VSS and VDD. Typically, these parts are used in a single-supply (positive) supply configuration. In this case, VSS is connected to ground and VDD is connected to the supply. VDD will need bypass capacitors. This is a CMOS, Schmitt-triggered input that places the MCP618 op amp into a low-power mode of operation. © 2008 Microchip Technology Inc. DS21613C-page 13 MCP616/7/8/9 NOTES: DS21613C-page 14 © 2008 Microchip Technology Inc. MCP616/7/8/9 4.0 APPLICATIONS INFORMATION The MCP616/7/8/9 family of op amps is manufactured using Microchip’s state-of-the-art CMOS process, which includes PNP transistors. These op amps are unity-gain stable and suitable for a wide range of general purpose applications. 4.1 Rail-to-Rail Inputs 4.1.1 VDD D1 V1 R1 R2 PHASE REVERSAL INPUT VOLTAGE AND CURRENT LIMITS The ESD protection on the inputs can be depicted as shown in Figure 4-1. 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 above VDD; their breakdown voltage is high enough to allow normal operation, and low enough to bypass quick ESD events within the specified limits. VDD Bond Pad R3 VSS – (minimum expected V1) 2 mA VSS – (minimum expected V2) R2 > 2 mA R1 > FIGURE 4-2: Inputs. Input Stage Bond VIN– Pad VSS Bond Pad FIGURE 4-1: Structures. Protecting the Analog It is also possible to connect the diodes to the left of resistors R1 and R2. In this case, current through the diodes D1 and D2 needs 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. A significant amount of current can flow out of the inputs when the common mode voltage (VCM) is below ground (VSS). (See Figure 2-36.) Applications that are high impedance may need to limit the usable voltage range. 4.1.3 VIN+ Bond Pad MCP61X V2 The MCP616/7/8/9 op amp is designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 2-36 shows the input voltage exceeding the supply voltage without any phase reversal. 4.1.2 D2 NORMAL OPERATION The inputs of the MCP616/7/8/9 op amps connect to a differential PNP input stage. The common mode input voltage range (VCMR) includes ground in single-supply systems (VSS), but does not include VDD. This means that the amplifier input behaves linearly as long as the common mode input voltage (VCM) is kept within the specified VCMR limits (VSS to VDD–0.9V at +25°C). Simplified Analog Input ESD In order to prevent damage and/or improper operation of these op amps, the circuit they are in must limit the currents and voltages at the VIN+ and VIN– pins (see “Absolute Maximum Ratings †” at the beginning of Section 1.0 “Electrical Characteristics”). Figure 4-2 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. © 2008 Microchip Technology Inc. 4.2 DC Offsets The MCP616/7/8/9 family of op amps have a PNP input differential pair that gives good DC performance. They have very low input offset voltage (±150 µV, maximum) at TA = +25°C, with a typical bias current of -15 nA (sourced out of the inputs). There must be a DC path to ground (or power supply) from both inputs, or the op amp will not bias properly. The DC resistances seen by the op amp inputs (R1||R2 and R4||R5 in Figure 4-3) need to be equal and less than 100 kΩ, to minimize the total DC offset.

Make sure the common mode input voltage range and output voltage range are not exceeded. 4.3 V1 GN Rail-to-Rail Output There are two specifications that describe the output swing capability of the MCP616/7/8/9 family of op amps. The first specification (Maximum Output Voltage Swing) defines the absolute maximum swing that can be achieved under the specified load conditions. For instance, the output voltage swings to within 15 mV of the negative rail with a 25 kΩ load tied to VDD/2. Figure 2-33 shows how the output voltage is limited when the input goes beyond the linear region of operation. The second specification that describes the output swing capability of these amplifiers is the Linear Output Voltage Range. This specification defines the maximum output swing that can be achieved while the amplifier still operates in its linear region. To verify linear operation in this range, the large-signal DC Open-Loop Gain (AOL) is measured at points inside the supply rails. The measurement must meet the specified AOL conditions in the specification table. © 2008 Microchip Technology Inc. MCP616/7/8/9 4.4 Capacitive Loads 4.5 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. A unity-gain buffer (G = +1) is the most sensitive to capacitive loads, though all gains show the same general behavior. When driving large capacitive loads with these op amps (e.g., > 60 pF when G = +1), a small series resistor at the output (RISO in Figure 4-5) improves the feedback loop’s phase margin (stability) by making the output load resistive at higher frequencies. The bandwidth will be generally lower than the bandwidth with no capacitive load. MCP618 Chip Select (CS) The MCP618 is a single op amp with Chip Select (CS). When CS is pulled high, the supply current drops to 50 nA (typical) and flows through the CS pin to VSS. When this happens, the amplifier output is put into a high-impedance state. By pulling CS low, the amplifier is enabled. The CS pin has an internal 5 MΩ (typical) pull-down resistor connected to VSS, so it will go low if the CS pins is left floating. Figure 1-1 shows the output voltage and supply current response to a CS pulse. 4.6 Supply Bypass 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. It may use a bulk capacitor (i.e., 1 µF or larger) within 100 mm to provide large, slow currents. This bulk capacitor is not required and can be shared with other analog parts. RISO VOUT MCP61X CL VIN FIGURE 4-5: Output Resistor, RISO stabilizes large capacitive loads. Figure 4-6 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). 4.7 Unused Op Amps An unused op amp in a quad package (MCP619) should be configured as shown in Figure 4-7. These circuits prevent the output from toggling and causing crosstalk. Circuits A sets the op amp at its minimum noise gain. The resistor divider produces any desired reference voltage within the output voltage range of the op amp; the op amp buffers that reference voltage. Circuit B uses the minimum number of components and operates as a comparator, but it may draw more current. ¼ MCP619 (A) Recommended RISO () 10,000 10k ¼ MCP619 (B) VDD R1 1k 1,000 GN = +1 GN t +2 100 100 10n 10p 100p 1n 1.E-11 1.E-10 1.E-09 1.E-08 Normalized Load Capacitance; C L/GN (F) FIGURE 4-6: 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.

DS21613C-page 17 MCP616/7/8/9 4.8 PCB Surface Leakage 4.9 In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity conditions, a typical resistance between nearby traces is 1012Ω. A 5V difference would cause 5 pA of current to flow, which is greater than the MCP616/7/8/9 family’s bias current at 25°C (1 pA, typical). The easiest way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is biased at the same voltage as the sensitive pin. An example is shown below in Figure 4-8. Guard Ring VIN– VIN+ 4.9.1 Application Circuits HIGH GAIN PRE-AMPLIFIER The MCP616/7/8/9 op amps are well suited to amplifying small signals produced by low-impedance sources/sensors. The low offset voltage, low offset current and low noise fit well in this role. Figure 4-9 shows a typical pre-amplifier connected to a lowimpedance source (VS and RS). VS RS 10 kΩ VDD/2 VSS RG RF 11.0 kΩ 100 kΩ FIGURE 4-9: FIGURE 4-8: for Inverting Gain. 1. 2. Example Guard Ring Layout Non-inverting Gain and Unity Gain Buffer: a) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface. b) Connect the guard ring to the inverting input pin (VIN–). This biases the guard ring to the common mode input voltage. Inverting Gain and Transimpedance gain (convert current to voltage, such as photo detectors) amplifiers: a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as the op amp (e.g., VDD/2 or ground). b) Connect the inverting pin (VIN–) to the input with a wire that does not touch the PCB surface. VOUT MCP616 High Gain Pre-amplifier. For the best noise and offset performance, the source resistance RS needs to be less than 15 kΩ. The DC resistances at the inputs are equal to minimize the offset voltage caused by the input bias currents (Section 4.2 “DC Offsets”). In this circuit, the DC gain is 10 V/V, which will give a typical bandwidth of 19 kHz. 4.9.2 TWO OP AMP INSTRUMENTATION AMPLIFIER The two-op amp instrumentation amplifier shown in Figure 4-10 serves the function of taking the difference of two input voltages, level-shifting it and gaining it to the output. This configuration is best suited for higher gains (i.e., gain > 3 V/V). The reference voltage (VREF) is typically at mid-supply (VDD/2) in a single-supply environment. 2R ⎞ R ⎛ VOUT = ( V 1 – V 2 ) ⎜1 + ------1 + ---------1- ⎟ + V REF R ⎝ 2 RG ⎠ RG R1 R2 R2 R1 VREF V2 VOUT ½ MCP617 ½ MCP617 V1 FIGURE 4-10: Two-Op Amp Instrumentation Amplifier. The key specifications that make the MCP616/7/8/9 family appropriate for this application circuit are low input bias current, low offset voltage and high commonmode rejection. DS21613C-page 18 © 2008 Microchip Technology Inc. MCP616/7/8/9 4.9.3 THREE OP AMP INSTRUMENTATION AMPLIFIER A classic, three-op amp instrumentation amplifier is illustrated in Figure 4-11. The two-input op amps provide differential signal gain and a common mode gain of +1. The output op amp is a difference amplifier, which converts its input signal from differential to a single-ended output; it rejects common mode signals at its input. The gain of this circuit is simply adjusted with one resistor (RG). The reference voltage (VREF) is typically referenced to mid-supply (VDD/2) in singlesupply applications. 2R ⎞ ⎛ R 4⎞ ⎛ VOUT = ( V 1 – V 2 ) ⎜1 + ---------2 ⎟ ⎜ ------⎟ + V REF R G ⎠ ⎝ R 3⎠ ⎝ V2 PRECISION GAIN WITH GOOD LOAD ISOLATION In Figure 4-12, the MCP616 op amp, R1 and R2 provide a high gain to the input signal (VIN). The MCP616’s low offset voltage makes this an accurate circuit. The MCP606 is configured as a unity-gain buffer. It isolates the MCP616’s output from the load, increasing the high gain stage’s precision. Since the MCP606 has a higher output current, and the two amplifiers are housed in separate packages, there is minimal change in the MCP616’s offset voltage due to loading effect.

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. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
