GENERAL DESCRIPTION

The AD7723 is a complete 16-bit, sigma-delta ADC. The part

operates from a 5 V supply. The analog input is continuously

sampled, eliminating the need for an external sample-and-hold.

The modulator output is processed by a finite impulse response

(FIR) digital filter. The on-chip filtering combined with a high

oversampling ratio reduces the external antialias requirements

to first order in most cases. The digital filter frequency response

can be programmed to be either low-pass or band-pass.

The part provides an on-chip 2.5 V reference. Alternatively, an

external reference can be used.

A power-down mode reduces the idle power consumption

to 200 µW.

The AD7723 provides 16-bit performance for input bandwidths

up to 460 kHz at an output word rate up to 1.2 MHz. The

sample rate, filter corner frequencies, and output word rate are

set by the crystal oscillator or external clock frequency.

The AD7723 is available in a 44-lead MQFP package and is

specified over the industrial temperature range from

–40°C to +85°C.

Data can be read from the device in either serial or parallel

format. A stereo mode allows data from two devices to share a

single serial data line. All interface modes offer easy, high speed

connections to modern digital signal processors.

Two input modes are provided, allowing both unipolar and

bipolar input ranges.
