SOFTWARE FULL RESET

The device can also be reset completely via software (see Table 26). When the register address is set to 1111, the device behaves in a

power-up state, where the output is clamped to AGND and the output buffer is powered down. The user must write to the control register

to configure the device, remove the 1 kΩ resistor clamp to ground, and power up the output buffer.

The software full reset command is also issued when the DAC output range is reconfigured during normal operation.
