1

REF

AI

Reference Input Voltage. The REF range is from 1 V to VDD. It is referred to the GND pin. This pin should be

decoupled closely to the pin with a ceramic capacitor of a few µF.

2

IN+

AI

Analog Input. It is referred to in IN−. The voltage range, i.e., the difference between IN+ and IN−, is 0 V

to VREF.

3

IN−

AI

Analog Input Ground Sense. To be connected to the analog ground plane or to a remote sense ground.

4

GND

P

Power Supply Ground.

5

CNV

DI

Convert Input. On its leading edge, it initiates the conversions. It enables the SDO pin when low.

6

SDO

DO Serial Data Output. The conversion result is output on this pin. It is synchronized to SCK.

7

SCK

DI

Serial Data Clock Input. When CNV is low, the conversion result is shifted out by this clock.

8

VDD

P

Power Supply.

1AI = analog input; DI = digital input; DO = digital output; and P = power.
