Driving a Capacitive Load

When the amplifier is configured in this manner, capacitive loading directly on the output will decrease the

device

’s phase margin leading to high frequency ringing or oscillations. Therefore, for capacitive loads of greater

than 10 pF, it is recommended that a resistor be placed in series (RNULL) with the output of the amplifier, as

shown in Figure 47. A minimum value of 20

Ω should work well for most applications.

Offset Voltage

The output offset voltage, (VOO) is the sum of the input offset voltage (VIO) and both input bias currents (IIB) times

the corresponding gains. The following schematic and formula can be used to calculate the output offset voltage:
