MCP6271/2/3/4/5 170 µA, 2 MHz Rail-to-Rail Op Amp Features Description • • • • • • • • The Microchip Technology Inc. MCP6271/2/3/4/5 family of operational amplifiers (op amps) provide wide bandwidth for the current. This family has a 2 MHz Gain Bandwidth Product (GBWP) and a 65° phase margin. This family also operates from a single supply voltage as low as 2.0V, while drawing 170 µA (typ.) quiescent current. Additionally, the MCP6271/2/3/4/5 supports rail-to-rail input and output swing, with a common mode input voltage range of VDD + 300 mV to VSS – 300 mV. This family of operational amplifiers is designed with Microchip’s advanced CMOS process. Gain Bandwidth Product: 2 MHz (typ.) Supply Current: IQ = 170 µA (typ.) Supply Voltage: 2.0V to 5.5V Rail-to-Rail Input/Output Extended Temperature Range: -40°C to +125°C Available in Single, Dual and Quad Packages Single with Chip Select (CS) (MCP6273) Dual with Chip Select (CS) (MCP6275) Applications • • • • • • The MCP6275 has a Chip Select input (CS) for dual op amps in an 8-pin package and is manufactured by cascading two op amps (the output of op amp A connected to the non-inverting input of op amp B). The CS input puts the device in Low-power mode. Automotive Portable Equipment Photodiode Amplifier Analog Filters Notebooks and PDAs Battery-Powered Systems The MCP6271/2/3/4/5 family operates over the Extended Temperature Range of -40°C to +125°C, with a power supply range of 2.0V to 5.5V.

This connection makes it possible to provide a CS pin for duals in 8-pin packages. DS21810D-page 10 3.4 CS Digital Input This is a CMOS, Schmitt-triggered input that places the part into a low-power mode of operation. 3.5 Power Supply (VSS and VDD) The positive power supply (VDD) is 2.0V 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 a local bypass capacitor (typically 0.01 µF to 0.1 µF) within 2 mm of the VDD pin. These parts need to use a bulk capacitor (within 100 mm), which can be shared with nearby analog parts. 2004 Microchip Technology Inc. MCP6271/2/3/4/5 4.0 APPLICATION INFORMATION – The MCP6271/2/3/4/5 family of op amps is manufactured using Microchip’s state-of-the-art CMOS process, specifically designed for low-cost, low-power and general purpose applications. The low supply voltage, low quiescent current and wide bandwidth makes the MCP6271/2/3/4/5 ideal for battery-powered applications. 4.1 RIN VIN ( Maximum expected V IN ) – VDD R IN ≥ ---------------------------------------------------------------------------------------2 mA V SS – ( Minimum expected V IN ) R IN ≥ -------------------------------------------------------------------------------------2 mA Rail-to-Rail Inputs The MCP6271/2/3/4/5 op amps are designed to prevent phase reversal when the input pins exceed the supply voltages. Figure 4-1 shows the input voltage exceeding the supply voltage without any phase reversal. FIGURE 4-2: Resistor (RIN). 4.2 Input, Output Voltage (V) 6 4 VOUT VIN Input Current Limiting Rail-to-Rail Output The output voltage range of the MCP6271/2/3/4/5 op amps is VDD – 15 mV (min.) and VSS + 15 mV (max.) when RL = 10 kΩ is connected to VDD/2 and VDD = 5.5V.

The input stage of the MCP6271/2/3/4/5 op amps use two differential CMOS input stages in parallel. One operates at low common mode input voltage (VCM) and the other at high VCM. With this topology, the device operates with VCM up to 0.3V above VDD and 0.3V below VSS. The Input Offset Voltage (VOS) is measured at VCM = VSS – 0.3V and VDD + 0.3V to ensure proper operation. Input voltages that exceed the absolute maximum voltage (VSS – 0.3V to VDD + 0.3V) can cause excessive current to flow into or out of the input pins. Current beyond ±2 mA can cause reliability problems. Applications that exceed this rating must be externally limited with a resistor, as shown in Figure 4-2. 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. 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., > 100 pF when G = +1), a small series resistor at the output (RISO in Figure 4-3) 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. – RISO MCP627X VIN + VOUT CL FIGURE 4-3: Output Resistor, RISO stabilizes large capacitive loads. Figure 4-4 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). 2004 Microchip Technology Inc.

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 MCP6271/2/3/4/5 SPICE macro model are helpful. MCP6273/5 Chip Select (CS) The MCP6273 and MCP6275 are single and dual op amps with Chip Select (CS), respectively. When CS is pulled high, the supply current drops to 0.7 µA (typ.) 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. If the CS pin is left floating, the amplifier may not operate properly. Figure 1-1 shows the output voltage and supply current response to a CS pulse. 4.5 6 1 10 4.4 VINB– VOUTA/VINB+ 1,000 Cascaded Dual Op Amps (MCP6275) The MCP6275 is a dual op amp with Chip Select (CS). The Chip Select input is available on what would be the non-inverting input of a standard dual op amp (pin 5). This pin is available because the output of op amp A connects to the non-inverting input of op amp B, as shown in Figure 4-5. The Chip Select input, which can be connected to a microcontroller I/O line, puts the device in Low-power mode. Refer to Section 4.4 “MCP6273/5 Chip Select (CS)”. FIGURE 4-5: Cascaded Gain Amplifier. The output of op amp A is loaded by the input impedance of op amp B, which is typically 1013Ω6 pF, as specified in the DC specification table (Refer to Section 4.3 “Capacitive Loads” for further details regarding capacitive loads). The common mode input range of these op amps is specified in the data sheet as VSS – 300 mV and VDD + 300 mV. However, since the output of op amp A is limited to VOL and VOH (20 mV from the rails with a 10 kΩ load), the non-inverting input range of op amp B is limited to the common mode input range of VSS + 20 mV and VDD – 20 mV. 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 also needs a bulk capacitor (i.e., 1 µF or larger) within 100 mm to provide large, slow currents. This bulk capacitor can be shared with other analog parts. 4.7 PCB Surface Leakage 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. This is greater than the MCP6271/2/3/4/5 family’s bias current at 25°C (1 pA, typ.). 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 of this type of layout is illustrated in Figure 4-6. DS21810D-page 12 2004 Microchip Technology Inc. MCP6271/2/3/4/5 VIN– VIN+ 4.8 VSS Guard Ring FIGURE 4-6: for Inverting Gain. 1. 2. Example Guard Ring Layout For Inverting Gain and Transimpedance Amplifiers (convert current to voltage, such as photo detectors): 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. 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. Application Circuits 4.8.1 ACTIVE FULL-WAVE RECTIFIER The MCP6271/2/3/4/5 family of amplifiers can be used in applications such as an Active Full-Wave Rectifier or an Absolute Value circuit, as shown in Figure 4-7. The amplifier and feedback loops in this active voltage rectifier circuit eliminate the diode drop problem that exists in a passive voltage rectifier. This circuit behaves as a follower (the output follows the input) as long as the input signal is more positive than the reference voltage. If the input signal is more negative than the reference voltage, however, the circuit behaves as an inverting amplifier. Therefore, the output voltage will always be above the reference voltage, regardless of the input signal.

DS21810D-page 13 MCP6271/2/3/4/5 4.8.2 LOSSY NON-INVERTING INTEGRATOR 4.8.3 The non-inverting integrator shown in Figure 4-8 is easy to build. It saves one op amp over the typical Miller integrator plus inverting amplifier configuration. The phase accuracy of this integrator depends on the matching of the input and feedback resistors, and the capacitor’s time constants. RF is used to provide feedback at frequencies << 1/(2 πR1C1) and makes this a lossy integrator (it has infinite gain at DC). R1 VIN + C1 MCP6271 _ RF VOUT C2 R2 CASCADED OP AMP APPLICATIONS The MCP6275 provides the flexibility of Low-power mode for dual op amps in an 8-pin package. The MCP6275 eliminates the added cost and space in a battery-powered application by using two single op amps with Chip Select (CS) lines or a 10-pin device with one CS line for both op amps. Since the two op amps are internally cascaded, this device cannot be used in circuits that require active or passive elements between the two op amps. However, there are several applications where this op amp configuration with a CS line becomes suitable. The circuits below show possible applications for this device. 4.8.3.1 Load Isolation With the cascaded op amp configuration, op amp B can be used to isolate the load from op amp A. In applications where op amp A is driving capacitive or low resistive loads in the feedback loop (such as an integrator or filter circuit) the op amp may not have sufficient source current to drive the load. In this case, op amp B can be used as a buffer. R 1 C 1 = ( R2 || RF )C 2 FIGURE 4-8: VOUTB B Non-Inverting Integrator. A MCP6275 Load CS FIGURE 4-9: Buffer. 4.8.3.2 Isolating the Load with a Cascaded Gain Figure 4-10 shows a cascaded gain circuit configuration with Chip Select. Op amps A and B are configured in a non-inverting amplifier configuration. In this configuration, it is important to note that the input offset voltage of op amp A is amplified by the gain of op amp A and B, as shown below: V OUT = V IN G A G B + V OSA G A G B + V OSB G B Where: GA = op amp A gain GB = op amp B gain VOSA = op amp A input offset voltage VOSB = op amp B input offset voltage Therefore, it is recommended that you set most of the gain with op amp A and use op amp B with relatively small gain (e.g., a unity-gain buffer).

In this configuration, it is recommended that well-matched resistors (e.g., 0.1%) be used to increase the Common Mode Rejection Ratio (CMRR). Op amp B can be used to provide additional gain and isolate the load from the difference amplifier.

Figure 4-12 uses an active compensator (op amp B) to compensate for the non-ideal op amp characteristics introduced at higher frequencies. This circuit uses op amp B as a unity-gain buffer to isolate the integration capacitor C1 from op amp A and drives the capacitor with a low-impedance source. Since both op amps are matched very well, they provide a high-quality integrator. 2004 Microchip Technology Inc.

R1 and R2 are used to set the circuit gain. R3 is used to set the Q. To avoid gain-peaking in the frequency response, Q needs to be low (lower values need to be selected for R3). Note that the amplifier bandwidth varies greatly over temperature and process. This configuration, however, provides a lowcost solution for applications with high bandwidth requirements.
