PRELIMINARY TECHNICAL DATA

AD74322

An on-chip reference voltage is included but can be

bypassed if required for use with an external reference

source.

T he AD74322 offers sampling rates which, depending on

MCLK selection and MCLK divider ratio, range from 8

kHz in the voiceband range to 96 kHz in the audio range.

T he digital interface to the AD74322 is configured as two

separate ports which allow separation of device control

and data streams. Control and status are monitored using

an SPI^®compatible serial port while the input and output

data streams are controlled using an I²S^®port. T he two

I²S streams are controlled by a common Bit-Clock and

Left/Right Clock pins. T here is also a DSP mode

available on the audio data port which will also allow both

control and data to be streamed through the same interface

where controller resources are limited.

T he AD74322 is available in various lead count package

options. T hese range from a 16-pin variant with single-

ended inputs/outputs and no SPI port through a 20-pin

variant with single-ended inputs/outputs and an SPI port

to a 24-pin variant with differential inputs/outputs and an

SPI port. T hese devices will be available in SOIC, SSOP

and T SSOP package options and are specified for the

industrial temperature range of -40°C to +85°C.
