Dual Sigma-Delta ADC

with Auxiliary DAC

AD7729

FEATURES

+3 V Supply Voltage

GENERAL DESCRIPTION

This monolithic 3 V CMOS device is a low power, two-channel,

input port with signal conditioning. The receive path is com-

posed of two high performance sigma-delta ADCs with digital

filtering. A common bandgap reference feeds the ADCs.

Baseband Serial Port (BSPORT)

Differential IRx and QRx

ADC Channels

Two 15-Bit Sigma-Delta A/D Converters

FIR Digital Filters

A control DAC is included for such functions as AFC. The auxil-

iary functions can be accessed via the auxiliary port (ASPORT).

64 dB SNR

Output Word Rate 270.83 kHz

Twos Complement Coding

On-Chip Offset Calibration

Power-Down Mode

This device is available in a 28-lead TSSOP package or a

28-lead SOIC package.

Auxiliary D/A Converter

Auxiliary Serial Port (ASPORT)

On-Chip Voltage Reference

Low Power

28-Lead TSSOP/28-Lead SOIC

APPLICATIONS

GSM Basestations
