Pin Functions

PIN TYPE DESCRIPTION
NAME NO.
CS 6 Digital I/O Chip select. On the falling edge of CS, a conversion process begins.
GND 2 PWR The ground return for the supply and signals.
SCLK 4 Digital I/O Digital clock input. This clock directly controls the conversion and readout processes.
SDATA 5 Digital I/O Digital data output. The output samples are clocked out of this pin on falling edges of the SCLK pin.
VA 1 PWR Positive supply pin. This pin must be connected to a quiet 2.7-V to 5.25-V source and bypassed to GND with a 1-µF capacitor and a 0.1-µF monolithic capacitor located within 1 cm of the power pin.
VIN 3 Analog I/O Analog input. This signal can range from 0 V to VA.
PAD — PWR For package suffix CISD(X) only, TI recommends connecting the center pad to ground.
