ADA4841-1:  Low Power, Low Noise and Distortion, Rail-to-Rail Output Amplifier

Product Description

The ADA4841-1 is a unity gain stable, low noise and distortion, rail-to-rail output amplifier that has a quiescent current of 1.5 mA maximum. Despite its low power consumption, this amplifier offers low wideband voltage noise performance of 2.1 nV/√Hz and 1.4 pA/√Hz current noise, along with excellent spurious-free dynamic range (SFDR) of -105 dBc at 100 kHz. To maintain a low noise environment at lower frequencies, the amplifier has low 1/f noise of 7 nV/√Hz and 13 pA/√Hz at 10 Hz.

The ADA4841-1 output can swing to less than 50 mV of either rail. The input common-mode voltage range extends down to the negative supply. The ADA4841-1 can drive up to 10 pF of capacitive load with minimal peaking.

The ADA4841-1 packages feature Pb-free lead finish. This amplifier is rated to work over the industrial temperature range (-40°C to +125°C).
