While the DAC80516 is capable of driving currents up to 50mA (with a short circuit current rating of 75mA), the device can be integrated into the circuit in Figure 8-2 to achieve a stable voltage output with even higher drive currents. In this application, the DAC programs the output voltage and gain of an amplifier. The amplifier maintains the output voltage using negative feedback. The high current to the load is provided by the transistor. This circuit is useful in applications where components must be tested with different voltage excitation levels at higher currents, including optical laser biasing applications (requiring over 50mA-75mA of bias current) as well as semiconductor test equipment.
