AD73322LYRZ

Overview

The AD73322LYRZ is a dual-channel analog front-end processor featuring two 16-bit ADCs and two 16-bit DACs. It operates on a single 2.7 V to 3.3 V supply with typical power consumption of 50 mW at 3.0 V. The device supports programmable sample rates up to 64 kHz, derived from a 16.384 MHz master clock. Key performance metrics include 78 dB SNR for both ADC and DAC channels, -90 dB crosstalk, and low group delay (25 µs per ADC channel). It integrates an on-chip reference, programmable gain networks, and a flexible serial port interface capable of cascading up to four devices.

Feature Summary

• Dual 16-bit ADC and DAC channels with 78 dB SNR
• Programmable input/output gains and sample rates (8/16/32/64 kHz)
• Low group delay: 25 µs (ADC), 50 µs (DAC)
• -90 dB interchannel crosstalk
• Single-supply operation (2.7 V to 3.3 V) with on-chip reference

Applications

• Speech processing and telephony
• Cordless and personal communications
• Active control of sound and vibration
• Data communications and wireless local loop

Procurement Notes

Verify the 'Y' suffix indicates the extended industrial temperature range (-40°C to +105°C). Confirm package type corresponds to the 'RZ' designation (28-lead SOIC). Check current availability status as distribution may vary.

Selection Notes

Select based on required sample rate (up to 64 kHz) and SNR requirements (78 dB). Ensure voltage levels match the 2.7 V to 3.3 V single-supply constraint. Verify serial interface compatibility with the host DSP or microcontroller.

Part Context

The AD73322L is part of Analog Devices' general-purpose analog front-end family. The Y-grade variant extends the operating temperature range to +105°C compared to the A-grade (+85°C). The RZ suffix specifies the 28-lead SOIC package.
