PRELIMINARY TECHNICAL DATA

AD74122

FUNCTIONAL DESCRIPTION

master or slave device. The AD74122 can also be set to operate

with sample rates of 8KHz to 48KHz depending on the values

of MCLK and the MCLK prescalers. On chip digital filtering

is provided for the DAC and ADC channels with a low group

delay option to reduce the delays through the filters when

operating at lower sample rates. Figure <modulators.eps>

shows a block diagram of a DAC and ADC channel in the

AD74122. Figure <filter.eps> shows a block diagram of the

filter arrangement of the ADC and DAC filters.

General Description

The AD74122 is a 2.5V stereo codec. It comprises two ADC

and two DAC channels with single ended inputs and outputs.

Signal conditioning and programmable gain stages are also

provided. Each of these sections are described in further detail

below. The AD74122 is controlled by means of a flexible serial

interface port (SPORT) which can be programmed to

accomodate many industry standard DSPs and

Microcontrollers. The AD74122 can be set to operate as a
