Pin Functions

PIN TYPE(1) DESCRIPTION
NO. NAME
1 VA P 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.
2 GND G The ground return for the supply and signals.
3 VIN I Analog input. This signal can range from 0 V to VA.
4 SCLK I Digital clock input. This clock directly controls the conversion and readout processes.
5 SDATA O Digital data output. The output samples are clocked out of this pin on falling edges of the SCLK pin.
6 CS I Chip select. On the falling edge of CS, a conversion process begins.
PAD GND G For package suffix CISD(X) only. TI recommends connecting the center pad to ground.
(1) G = Ground, I = Input, O = Output, P = Power
