AD7729ARU-REEL7

ADCs/DACs - Special Purpose Overview

The AD7729ARU-REEL7 is a monolithic 3 V CMOS dual-channel baseband codec featuring two 15-bit sigma-delta analog-to-digital converters (ADCs) and a 10-bit auxiliary digital-to-analog converter (DAC). It operates with a master clock of 13 MHz, providing an output word rate of 270.83 kHz. The device includes on-chip FIR digital filters, an internal bandgap voltage reference, and offset calibration capabilities. It supports differential or single-ended inputs via Baseband and Auxiliary Serial Ports within a 28-lead TSSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Dual 15-bit Sigma-Delta ADCs with integrated 288-tap FIR digital filters
• 10-bit Auxiliary DAC for functions such as Automatic Gain Control
• Internal 1.3 V Bandgap Voltage Reference with REFCAP and REFOUT pins
• On-chip Offset Calibration for I and Q channels

ADCs/DACs - Special Purpose Applications

• GSM Basestations
• Pagers

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'RU' indicates the 28-lead Thin Shrink Small Outline (TSSOP) package. Confirm the temperature range corresponds to the Industrial grade (-40°C to +105°C). Ensure the reel packaging matches production requirements.

ADCs/DACs - Special Purpose Selection Notes

Select this component for low-power baseband signal processing requiring high-resolution I/Q demodulation. The 15-bit resolution and 64 dB SNR are suitable for narrowband applications. Verify that the 3 V supply voltage aligns with system power constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7729 family of baseband codecs. The 'ARU' designation specifies the Industrial temperature range and TSSOP-28 package. The '-REEL7' suffix denotes tape and reel packaging for automated assembly.
