The ADA4941-1 is a low power single-ended-to-differential converter that features ultralow distortion, low noise, extremely low power, high input impedance, easy-to-use gain adjustment, high speed, fast settling time, rail-to-rail output, disable function, and is available in space-saving packaging. It is suitable for single supply data acquisition systems, instrumentation, process control, battery-powered systems, and medical instruments.
The ADA4941-1 is a low‑power, single‑supply differential driver designed to convert a single‑ended input to a differential output for 16‑ to 18‑bit ADCs. It offers ultralow distortion (105 dBc THD at 10 kHz), high SNR (91 dB at 100 kHz), rail‑to‑rail output, and a gain of 2 V/V without external components.
The device operates from a wide supply range of 2.7 V to 12 V, draws only 2.1 mA typical quiescent current, and is available in compact 8‑lead LFCSP and SOIC packages. It is suited for single‑supply data‑acquisition systems, instrumentation, process control, battery‑powered instruments, and medical devices.
