Schematic Diagram
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/s; 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.
