PRODUCTION DATA.
The DACx1408 DAC output amplifiers and internal reference power-down status can be individually configured and monitored though the PWDWN registers. Setting a DAC channel in power-down mode disables the output amplifier and clamps the output pin to ground through an internal 10-kΩ resistor.
The DAC data registers are not cleared when the DAC goes into power-down which makes it possible to have the same output voltage upon return to normal operation. The DAC data registers can also be updated while in power-down mode.
After a power-on or reset event all the DAC channels and the internal reference are in power-down mode. The entire device can be configured into power-down or active modes through the DEV-PWDWN bit.
