HA-2529
Typical Application
Inverting Unity Gain Circuit
Figure 6 shows a Compensation Circuit for an inverting unity
gain amplifier. The circuit was tested for functionality with
supply voltages from ±4V to ±15V, and the performance as
tested was: Slew Rate ≈ 120V/µs; Bandwidth ≈ 10MHz; and
Settling Time (0.1%) ≈ 500ns. Figure 7 illustrates the
amplifier’s frequency response, and it is important to note that
capacitance at pin 8 must be minimized for maximum
bandwidth.
