SBAS438C May 2008 – November 2019 DAC9881
The DAC9881 has a hardware power-down feature. When the PDN pin is high, the device is in power-down mode. When the device is in power-down, the VOUT pin is connected to ground through an internal 10kΩ resistor, but the contents of the input register and the DAC latch do not change and SPI communication remains active. When the PDN pin returns low, the device returns to normal operation.
