This product is a high voltage differential 18-bit ADC driver that has the function of single-ended input-differential output. It has low distortion, low noise, high input impedance, fixed gain of 2, low output offset voltage, low input bias current, wide supply range, high speed, fast settling time, space saving and other features. It is suitable for high voltage data acquisition systems, industrial instrumentation, spectrum analyzers and other applications.
The ADA4922-1 differential driver converts single‑ended signals to differential outputs for 16‑ to 18‑bit ADCs with input ranges up to +20 V. It is intended for high‑voltage data acquisition, industrial instrumentation, spectrum analysis, ATE and medical instruments.
Key features include a fixed gain of 2, low distortion (‑99 dBc at 100 kHz), low output‑referred offset (1.1 mV typ), high input impedance (11 MΩ), and operation from 5 V to 26 V. The device is offered in 8‑lead 3 mm × 3 mm LFCSP and 8‑lead SOIC packages with exposed pads for efficient heat dissipation.
