Description
1
REF
AI
Reference Input Voltage. The REF range is from 0.5 V to VDD. This pin is referred to the GND pin and
should be decoupled closely to the GND pin with a ceramic capacitor of a few μF.
2
+IN
AI
Differential Positive Analog Input. Referenced to IN. The input range for +IN is between 0 V and VREF,
centered about VREF/2 and must be driven 180° out of phase with IN.
3
–IN
AI
Differential Negative Analog Input. Referenced to +IN. The input range for IN is between VREF and 0 V,
centered about VREF/2 and must be driven 180° out of phase with +IN.
4
GND
P
Power Supply Ground.
5
CS
DI
Chip Select Input. On its falling edge, it initiates the conversions. The part returns to shutdown mode as
soon as the conversion is complete. It also enables DOUT. When high, DOUT is high impedance.
6
DOUT
DO
Serial Data Output. The conversion result is output on this pin. It is synchronized to DCLOCK.
7
DCLOCK
DI
Serial Data Clock Input.
8
VDD
P
Power Supply.
1 AI = analog input, DI = digital input, DO = digital output, and P = power.
