8.2.1.2 Detailed Design Procedure

In this design example, the OPA593 is configured as both a gain stage and output driver. The input signal to the amplifier is 0 V to 5 V, and the device is configured with a positive gain of 8. This configuration results in an output voltage of 0 V to 40 V. Select supply voltages that provide adequate headroom so that the amplifier can sink or source up to 250 mA without slamming the output into the rail. Minimize the swing from the supply to the output to minimize the thermal dissipation of the device.

This simple design example is common in many systems that use a DAC to provide the input signal and require a wide output signal with high output current. Such systems include test and measurement platforms and power supplies.

Figure 8-2 shows the input and output signal of this OPA593 circuit.
