... AD5390/AD5391/AD5392 Mnemonic Function PD Power-Down (level-sensitive, active high). Used to place the device in low power mode, in which the device consumes 1 μA analog current and 20 μA digital current. In power-down mode, all internal analog circuitry is placed in low power mode; the analog output is configured as high impedance outputs or provides a 100 kΩ load to ground, depending on how the power-down mode is configured ...
