AD1674 is a 12-bit 100 kSPS analog-to-digital converter with on-board sample-and-hold amplifier and 8- and 16-bit microprocessor interface.
The AD1674 is a complete, multipurpose 12‑bit A/D converter featuring an on‑board sample‑and‑hold amplifier, industry‑standard pinout, and flexible digital interfaces for 8‑ and 16‑bit microprocessors. It is offered in several temperature‑grade versions (A, B, J, K, T) and in plastic DIP, SOIC, and hermetic ceramic packages.
The datasheet provides detailed electrical specifications, timing diagrams, pin descriptions, and ordering information. Key performance figures include 100 kSPS sampling, up to 1 MHz full‑power bandwidth, and low power dissipation (≈ 400 mW).
