Analog Devices AD7822/AD7825/AD7829 Datasheet
The AD7822, AD7825, and AD7829 are high‑speed 8‑bit analog‑to‑digital converters offering 1, 4, or 8 single‑ended input channels, on‑chip 2.5 V reference, track‑and‑hold, and a fast 420 ns conversion time. They operate from a single 3 V ± 10 % or 5 V ± 10 % supply and include automatic power‑down at the end of conversion.
The datasheet details functional block diagrams, pin configurations, timing characteristics, absolute maximum ratings, and full electrical specifications such as resolution, SNR, THD, supply current, and power dissipation. Ordering information, package options, and typical connection diagrams are also provided.
