Note: The absolute maximum ratings (see page 3) for power dissipation and output short-circuit duration (10s, max)

must be adhered to since the output current can exceed 200mA (see Typical Operating Characteristics on

page 6).

Input Capacitance

(6pF typ). This introduces a pole at frequency (2

resistors for the inverting or non-inverting amplifier configuration (Figure 25). If the pole frequency is less than or com-

parable to the unity-gain bandwidth (10MHz), the phase margin is reduced, and the amplifier exhibits degraded AC

performance through either ringing in the step response or sustained oscillations.

The pole frequency is 10MHz when R

To improve step response when R

can be calculated by:

R is the gain-setting resistor.
