Analog Devices AD204 Isolation Amplifier Handbook
The AD204 isolation amplifier is a low‑power, miniature isolation device offering up to +2000 V peak continuous common‑mode isolation, 130 dB CMR at a gain of 100 V/V, and a 5 kHz full‑power bandwidth. It includes an uncommitted input op‑amp and can supply isolated +7.5 V power at 2 mA for auxiliary circuits.
The handbook covers functional block diagrams, power options (the AD204 is powered by an external clock driver such as the AD246), detailed specifications, wiring examples, adjustment procedures, and performance notes on common‑mode rejection, noise, and output filtering.
