Product details
Overview
AD7672UQ10 from Analog Devices is a 16-bit, 100 kSPS successive approximation register (SAR) analog-to-digital converter (ADC) in a 28-lead CERDIP package, featuring ±1 LSB integral nonlinearity, 86 dB SNR, and parallel interface with 5 V logic compatibility. It is used in precision data acquisition systems for industrial process control.
For engineers reviewing the AD7672UQ10 datasheet, AD7672UQ10 pinout, AD7672UQ10 application, or AD7672UQ10 equivalent, key selection considerations include sampling rate, INL performance, supply voltage range, parallel bus timing, and military-grade packaging suitability.
Technical Context
The AD7672UQ10 implements a SAR architecture with internal track-and-hold and reference buffer, supporting unipolar 0 V to +10 V input range. It operates from ±12 V analog supplies and +5 V digital supply, with conversion time fixed at 10 μs.
It uses a 16-bit parallel CMOS output bus with separate BUSY and RDY signals, and requires external reference voltage (typically +10 V). No internal reference or serial interface is provided.
Key Specifications

| INL | ±1 LSB max - ensures monotonicity and minimal code-width error across full scale |
| SNR | 86 dB - enables detection of signals buried ~12 bits below full-scale noise floor |
| Analog Supply | ±12 V - requires dual-rail op-amp-compatible power for signal conditioning front-end |
| Digital Supply | +5 V - interfaces directly with legacy TTL/CMOS logic without level-shifting |
| Input Range | 0 V to +10 V unipolar - matches standard industrial sensor output ranges |
Pinout & Package
AD7672UQ10 is housed in a hermetically sealed 28-lead ceramic DIP (CERDIP) package rated for −55°C to +125°C operation, suitable for military and aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| RDY | Conversion ready indicator | Active-high signal asserts when conversion completes and data is latched |
| BUSY | Conversion in progress flag | Active-high during sample/hold and conversion; used for handshaking |
| CS | Chip select | Active-low enable for parallel bus access; gates DB0–DB15 output drivers |
| REF IN | Reference voltage input | Accepts external +10 V reference; sets full-scale input range |
| AGND / DGND | Analog and digital ground | Separate pins minimize digital switching noise coupling into analog path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-precision, low-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7671UQ10 | Same 16-bit SAR core but 200 kSPS sampling rate; identical CERDIP-28 package and pinout | Used where higher throughput is needed without sacrificing DC accuracy | Select AD7671UQ10 if system requires >100 kSPS while retaining same form factor and interface |
| AD7682BCPZ | 16-bit, 250 kSPS SAR ADC in 20-lead LFCSP; includes internal reference and SPI interface | Targets space-constrained, modern designs requiring serial interface and reduced BOM count | Choose AD7682BCPZ for commercial/mid-temp applications where hermetic packaging is not required |
Compared with AD7672UQ10, AD7671UQ10 offers double the sampling rate in identical packaging, while AD7682BCPZ trades military-grade reliability and parallel interface for compact size, integrated reference, and SPI flexibility-making each suitable for distinct design priorities.

FAQ
What is the operating temperature range of the AD7672UQ10?
The AD7672UQ10 is specified for operation from −55°C to +125°C. This extended range is enabled by its hermetically sealed 28-lead CERDIP package and internal circuit design qualified for military and aerospace use. The AD7672UQ10 maintains full performance specifications-including ±1 LSB INL and 86 dB SNR-across this entire range without derating.
Does the AD7672UQ10 include an internal voltage reference?
No, the AD7672UQ10 requires an external precision reference voltage applied to the REF IN pin. It is typically used with a +10 V reference to support its 0 V to +10 V unipolar input range. The AD7672UQ10 does not integrate any reference circuitry, which preserves accuracy by allowing users to select a reference matched to their system's stability and drift requirements.
Is the AD7672UQ10 pin-compatible with other devices in the AD76xx family?
The AD7672UQ10 shares the same 28-lead CERDIP package and pinout with the AD7671UQ10, making them mechanically and electrically interchangeable. However, it is not pin-compatible with AD7682BCPZ or AD7690 due to different packages, pin counts, and interface types. Always verify pin assignments using the official AD7672UQ10 datasheet before board reuse.
What digital interface does the AD7672UQ10 support?
The AD7672UQ10 supports a 16-bit parallel CMOS interface with dedicated RDY and BUSY handshake signals. It operates with +5 V logic levels and does not support SPI, I²C, or other serial protocols. Data is output MSB-first on DB0–DB15, and read timing is controlled via CS and RDY signals-requiring no clock synchronization beyond standard parallel bus protocols.
Can the AD7672UQ10 be used in new designs despite its obsolete status?
Yes, the AD7672UQ10 remains available through Aetrix Electronics with full traceable sourcing and long-term supply assurance. While marked obsolete by Analog Devices, it continues to be supported for legacy system repair, military sustainment, and aerospace programs where qualification stability and known reliability outweigh newer alternatives. The AD7672UQ10 is actively managed under lifecycle continuity programs.
