The ADA4841-1/ADA4841-2 are low power, low noise and distortion, rail-to-rail output amplifiers with 1.1 mA/amp low power, 2.1 nV/√Hz low wideband noise, 7 nV/√Hz low 1/f noise, -105 dBc @ 100 kHz low distortion, 80 MHz high speed, 12 V/μs maximum slew rate and 0.3 mV maximum offset voltage. They are suitable for low power, low noise signal processing, battery-powered instrumentation and 16-bit PulSAR® ADC drivers.
The ADA4841-1 and ADA4841-2 are unity‑gain stable, low‑power, low‑noise, rail‑to‑rail output amplifiers. They consume a maximum of 1.5 mA quiescent current, offer a wide supply range of 2.7 V to 12 V, and deliver low offset voltage (0.3 mV max) with low 1/f noise.
The document includes feature tables, connection diagrams, detailed specifications, absolute maximum ratings, thermal resistance data, typical performance curves, power‑down operation details, and an ordering guide for the various package options.
