Function
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 k load to ground, depending on
how the power-down mode is configured. The serial interface remains active during power-down.
Interface Select Input Pin. When this input is low, I
2
C mode is selected. When this input is high, SPI mode is selected.
Interface CLOCK Input Pin. In SPI-compatible serial interface mode, this pin acts as a serial clock input. It operates at
clock speeds up to 50 MHz.

C mode is
compatible with both 100 kHz and 400 kHz operating modes.
Interface Data Input Pin.
