The AD1674 is a complete, multipurpose, 12-bit analog-to- digital converter, consisting of a user-transparent onboard sample-and-hold amplifier (SHA), 10 volt reference, clock and three-state output buffers for microprocessor interface. The AD1674 is pin compatible with the industry standard AD574A and AD674A, but includes a sampling function which eliminates timing errors in the conversion process.
The AD1674 is a 12‑bit analog‑to‑digital converter with a 100 kSPS sampling rate, featuring an on‑board sample‑and‑hold amplifier, industry‑standard pinout, and both unipolar and bipolar input ranges. It is offered in multiple temperature grades and package types for commercial, industrial, and military applications.
The document provides detailed specifications, pin descriptions, timing diagrams, and ordering information, enabling designers to integrate the AD1674 into signal‑processing or measurement systems.
