Typical Application (continued)

Figure 11. Voltage Division in the Difference Amplifier Configuration

The INA592 has integrated ESD diodes at the inputs that provide overvoltage protection. This feature simplifies

system design by eliminating the need for additional external protection circuitry, and enables a more robust

system. The voltages at any of the inputs of the parts in G = ½ configuration with ±18 V supplies can safely

V.

8.2.2.4 Capacitive Load Drive Capability

The INA592 can drive large capacitive loads, even at low supplies. It is stable with a 500-pF load. Refer to the

typical performance curves.

8.2.2.5 Other Examples for Difference Amplifier Configurations

The INA592 can be combined with op amps to form a complete instrumentation amplifier with specialized

performance characteristics, as shown in Figure 12.
