PAGE 17
MCP6021/1R/2/3/4 4.0 APPLICATIONS INFORMATION VDD The MCP6021/1R/2/3/4 family of operational amplifiers are fabricated on Microchip’s state-of-the-art CMOS process. They are unity-gain stable and suitable for a wide range of general-purpose applications. 4.1 D1 V1 R1 Rail-to-Rail Input 4.1.1 R2 R3 VSS – (minimum expected V1) 2 mA VSS – (minimum expected V2) R2 > 2 mA R1 > INPUT VOLTAGE AND CURRENT LIMITS The ESD protection on the inputs can be depicted as shown in Figure 4-1.
PAGE 18
MCP6021/1R/2/3/4 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 4-3) improves the feedback loop’s phase margin (stability) by making the load resistive at higher frequencies. The bandwidth will be generally lower than the bandwidth with no capacitive load. VIN 1 V/V (unity gain). CG also reduces the phase margin of the feedback loop for both non-inverting and inverting gains.

MCP6021/1R/2/3/4 4.6 MCP6021 and MCP6023 Reference Voltage RG VOUT VIN The single op amps (MCP6021 and MCP6023), not in the SOT-23-5 package, have an internal mid-supply reference voltage connected to the VREF pin (see Figure 4-7). The MCP6021 has CS internally tied to VSS, which always keeps the op amp on and always provides a mid-supply reference. With the MCP6023, taking the CS pin high conserves power by shutting down both the op amp and the VREF circuitry.

MCP6021/1R/2/3/4 4.9 PCB Surface Leakage In applications where low input bias current is critical, PCB (printed circuit board) 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 MCP6021/1R/2/3/4 family’s bias current at +25°C (1 pA, typical).

MCP6021/1R/2/3/4 4.11.2 OPTICAL DETECTOR AMPLIFIER Figure 4-13 shows the MCP6021 op amp used as a transimpedance amplifier in a photo detector circuit. The photo detector looks like a capacitive current source, so the 100 kΩ resistor gains the input signal to a reasonable level. The 5.6 pF capacitor stabilizes this circuit and produces a flat frequency response with a bandwidth of 370 kHz. 5.6 pF Photo Detector 100 kΩ 100 pF MCP6021 VDD/2 FIGURE 4-13: Transimpedance Amplifier for an Optical Detector.
