MCP6231 Shows
input stage MCP6231 uses differential input stages parallel. operates common mode input voltage (VCM) other high VCM. With this topology, device operates with above below VSS. Input Offset Voltage measured ensure proper operation. Input voltages that exceed input voltage range (VSS 0.3V 0.3V 25°C) cause excessive current flow into input pins. Current beyond cause reliability problems. Applications that exceed this rating must externally limited with resistor, shown Figure 3-2.
Driving large capacitive loads cause stability problems voltage feedback amps. load capacitance increases, feedback loop's phase margin decreases closed-loop bandwidth reduced. This produces gain peaking frequency response, with overshoot ringing step response. unity-gain buffer most sensitive capacitive loads, gains show same general behavior. When driving large capacitive loads with these amps (e.g., when +1), small series resistor output (RISO Figure 3-3) improves feedback loop's phase margin (stability) making output load resistive higher frequencies. does not, however, improve bandwidth.

Example Guard Ring Layout
Supply Bypass
With this amp, power supply (VDD singlesupply) should have local bypass capacitor (i.e., 0.01 within good high-frequency performance. also needs bulk capacitor (i.e., larger) within provide large, slow currents. This bulk capacitor shared with other parts.
Surface Leakage
applications where input bias current critical, (printed circuit board) surface leakage effects need considered. Surface leakage caused humidity, dust other contamination board. Under humidity conditions, typical resistance between nearby traces 1012. difference would cause current-to-flow. This greater than MCP6231 family's bias current 25°C typ).
Non-inverting Gain Unity-Gain Buffer: Connect non-inverting (VIN+) input with wire that does touch surface. Connect guard ring inverting input (VIN-). This biases guard ring common mode input voltage. Inverting transimpedance gain amplifiers (convert current voltage, such photo detectors): Connect guard ring non-inverting input (VIN+). This biases guard ring same reference voltage (e.g., VDD/2 ground). Connect inverting (VIN-) input with wire that does touch surface.
