MCP6001/2/4

This voltage rate of change is less than the MCP6001/2/4

slew rate of 0.6 V/µs. When the input voltage swings

below the voltage across C1, D1 becomes reverse-

biased. This opens the feedback loop and rails the

amplifier. When the input voltage increases, the amplifier

recovers at its slew rate. Based on the rate of voltage

change shown in the above equation, it takes an

extended period of time to charge a 0.1 µF capacitor. The

capacitors need to be selected so that the circuit is not

limited by the amplifier slew rate. Therefore, the capaci-

tors should be less than 40 µF and a stabilizing resistor

(RISO) needs to be properly selected. (Refer to

Section 4.3 “Capacitive Loads”).
