AD7729ARUZ-REEL7

ADCs/DACs - Special Purpose Overview

The AD7729ARUZ-REEL7 is a monolithic dual-channel Sigma-Delta ADC with an auxiliary DAC, designed for low-power 3 V operation. It features two 15-bit receive channels (IRx and QRx) sampling at 13 MSPS with a digital output word rate of 270.83 kHz. The device integrates on-chip FIR digital filters providing 64 dB SNR and offset calibration capabilities. A 10-bit auxiliary DAC supports functions like AGC. Powered by a single 3 V supply, it operates within a temperature range of -40°C to +105°C and is housed in a 28-lead TSSOP package.

ADCs/DACs - Special Purpose Applications

• GSM Basestations
• Pagers

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix REEL7 against the manufacturer's ordering guide to confirm tape-and-reel packaging. Confirm that the ARUZ designation corresponds to the RU-28 (TSSOP) package variant. Check current lifecycle status as discontinued products may require alternative sourcing strategies.

ADCs/DACs - Special Purpose Selection Notes

Select this component for baseband signal processing requiring differential I/Q reception. Ensure the system provides a 13 MHz master clock. Verify that the 2 V peak-to-peak ADC signal range and 1.3 V internal reference align with the sensor interface requirements.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AD7729 family of baseband codecs. It is functionally identical to the AD7729ARZ but utilizes a TSSOP package instead of SOIC. Both variants share the same electrical specifications and pinout configuration for dual-channel data acquisition.

ADCs/DACs - Special Purpose Replacement Considerations

The AD7729ARZ is a direct pin-compatible replacement offering the same functionality in a SOIC-28 package. No functional changes are required when substituting between package types.
