This document describes a low power, gain greater than or equal to 10, stable rail-to-rail output amplifier called ADA4895-2. The amplifier features low wideband noise, low 1/f noise, low distortion, high speed, and a wide supply range.
The ADA4895-2 is a gain‑10 stable, low‑noise voltage‑feedback amplifier featuring rail‑to‑rail output, high speed, and a quiescent current of 3 mA. It operates from a wide supply range of 3 V to 10 V and is offered in a 10‑lead MSOP package suitable for industrial temperature ranges.
Key performance figures include a –3 dB bandwidth of up to 140 MHz at a gain of +10, a slew rate of 500 V/µs, and input voltage noise as low as 1 nV/√Hz at 100 kHz. The device also provides a disable pin for power‑saving operation.
| Slew Rate (G=+10, Vout=2 V p‑p) | 500 V/µs |
|---|---|
| Supply Voltage Range | 3 V to 10 V |
| Quiescent Current per Amplifier | 3.2 mA |
It operates from 3 V up to 10 V.
Each amplifier draws about 3.2 mA of quiescent current.
Yes, the device includes a disable pin; when the pin voltage is above +Vs the amplifier is enabled, and when it is below +Vs the amplifier is disabled.
