Analog Devices AD7819 Datasheet
The AD7819 is a high‑speed, microprocessor‑compatible 8‑bit analog‑to‑digital converter offering up to 200 kSPS throughput. It operates from a single 2.7 V to 5.5 V supply and includes on‑chip track‑and‑hold, a charge‑redistribution DAC, and an 8‑bit parallel interface for easy connection to microprocessors and DSPs.
The device features automatic power‑down to reduce consumption in low‑throughput applications, and it is available in three package types: 16‑lead DIP, SOIC, and TSSOP. Detailed specifications cover dynamic performance, power consumption, timing, and absolute maximum ratings.
