ADA4841-1/ADA4841-2 are low power, low noise and distortion, rail-to-rail output amplifiers.
The ADA4841‑1 and ADA4841‑2 are unity‑gain stable, low‑noise, low‑distortion rail‑to‑rail output amplifiers. They consume only about 1.1 mA quiescent current while delivering a typical 80 MHz –3 dB bandwidth, 12 V/µs slew rate, and 175 ns settling time to 0.1 %.
These amplifiers are suited for battery‑powered instrumentation, 16‑bit PulSAR ADC drivers, and other high‑precision measurement applications. They are offered in 8‑lead SOIC, 6‑lead SOT‑23, 8‑lead MSOP, and 8‑lead LFCSP packages, with an operating supply range of 2.7 V to 12 V and a temperature range of –40 °C to +125 °C. The document includes connection diagrams, ordering guide, and typical performance graphs.
