AD7329

Data Sheet

Pin No.

Descriptions

21

Logic Power Supply Input. The voltage supplied at this pin determines at what voltage the interface operates.

by more than 0.3 V.

22

DOUT

Serial Data Output. The conversion output data is supplied to this pin as a serial data stream. The bits are

clocked out on the falling edge of the SCLK input, and 16 SCLKs are required to access the data. The data

stream consists of three channel identification bits, the sign bit, and 12 bits of conversion data. The data is

provided MSB first (see the Serial Interface section).

24

SCLK

Serial Clock, Logic Input. A serial clock input provides the SCLK used for accessing the data from the AD7329.

This clock is also used as the clock source for the conversion process.
