NAME
DESCRIPTION
1
V_A
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 placed within 1 cm of the power pin.
2
GND
G The ground return for the supply and signals.
3
V_IN
I
Analog input. This signal can range from 0 V to V_A.
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.
(1) G = Ground, I = Input, O = Output, P = Power
