Product Details
AD7002AS - GSM Baseband I/O Port
Analog Devices AD7002AS is a two-channel GSM baseband input/output and signal-conditioning IC in a 44-lead plastic quad flat package (PQFP, S-44). It combines transmit GMSK generation and D/A conversion with receive A/D conversion and digital filtering.
Analog Devices labels the AD7002 product obsolete. Verify traceable remaining inventory and the complete system interface before using this part in a design.
Overview
The AD7002AS forms a baseband conversion bridge between digital signal processing and the IF/RF section of a GSM terminal. Its transmit path includes a GMSK digital modulator, two 10-bit DACs and reconstruction filtering. Its receive path uses two sigma-delta ADCs and digital FIR filtering. Three auxiliary DACs support control functions such as AFC, AGC and carrier shaping.
Key Advantages
Integrated transmit chain
GMSK modulation, dual transmit DACs and reconstruction filters reduce separate baseband building blocks.
Integrated receive chain
Two sigma-delta conversion paths and digital filtering provide I/Q receive data to the host.
Auxiliary control
Three on-chip auxiliary DACs and AUX FLAG support surrounding RF-control functions.
Power management
Separate sleep controls for transmit, receive and auxiliary sections allow subsystem-level shutdown.
Feature Summary
Transmit
GMSK pulse shaping; I/Q analog outputs from two 10-bit DACs; on-chip reconstruction filters.
Receive
Two sigma-delta ADCs, digital FIR filtering and serial receive data/interface control.
Control
Three auxiliary DACs, auxiliary serial interface, control flag and on-chip reference.
Ordering
AD7002AS is the S-44 plastic quad-flatpack ordering code listed for the -40°C to +85°C grade in the AD7002 data sheet.
Package & Footprint
The product database registers 44-QFP; the Analog Devices ordering guide identifies AD7002AS as a 44-lead plastic quad flatpack, package option S-44. Verify the package outline and land pattern against the controlled drawing before layout.
- Confirm S-44 body dimensions and lead pitch.
- Check pin 1 orientation against the top-view pin diagram.
- Separate analog and digital return routing according to the data sheet.
- Review ESD handling and assembly suitability for legacy material.
The registered 44-QFP JPG is not present in the local package folder; this illustration remains unavailable until the approved file is supplied.
Pin Functions
Selected functions below follow the Analog Devices AD7002 Rev. B 44-lead PQFP pin description; use the full pin table for schematic sign-off.
Pin names and directions are device-specific. Check sleep, test and no-connect pin instructions in the manufacturer data sheet before wiring.

Replacement Considerations
No manufacturer-approved drop-in replacement for the exact AD7002AS order code was confirmed. A redesign must compare the GMSK transmit path, two-channel receive conversion, auxiliary DAC behavior, reference, 13 MHz clocking, host data format, supply rails, temperature grade and S-44 footprint. Generic GSM or audio-converter parts should not be treated as pin-compatible substitutes.
No internal substitute link is shown because no exact, manufacturer-supported replacement was confirmed.
Manufacturer Information
Analog Devices is the manufacturer named in the product record and the AD7002 documentation. The official AD7002 product page currently identifies the family as obsolete. Distributor inventory labels should not override the manufacturer lifecycle statement.
Applications
Legacy GSM equipment
Service and sustainment of systems originally designed around the AD7002 interface.
Baseband conversion
Transmit/receive conversion between digital processing and a compatible IF/RF chain.
Quality & Authenticity
For this obsolete device, confirm supplier authorization or traceable chain of custody, date code, package markings and ESD handling. Request an exact-lot quotation and check rework or long-storage risk before procurement. RoHS status must be verified for the actual material lot.
FAQ
What is AD7002AS?
A 44-lead PQFP GSM baseband I/O IC with integrated transmit and receive conversion paths.
Is AD7002AS recommended for new designs?
No. Analog Devices marks the AD7002 family obsolete; qualify an architecture-level redesign.
Can another converter replace it directly?
No direct interchangeability was confirmed. The digital interface, RF-control functions and footprint must be reviewed.
Is the package illustration ready?
No. The registered 44-QFP JPG is missing.
Engineering Notice
Check the Analog Devices AD7002 data sheet, exact S-44 package drawing and device lifecycle before approval. The current package JPG is unavailable, distributor listings conflict with the manufacturer obsolete status, and live inventory and price breaks have not been verified. Keep this page unpublished until those items are resolved.
