General Description
ADA4841-2 General Description
The ADA4841-1/ADA4841-2 are unity gain stable, low noise and distortion, rail-to-rail output amplifiers that have a quiescent current of 1.5 mA maximum. Despite their low power consumption, these amplifiers offer 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 amplifiers have low 1/f noise of 7 nV/Hz and 13 pA/Hz at 10 Hz.
The ADA4841-1/ADA4841-2 output can swing to less than 100 mV of either rail. The input common-mode voltage range extends down to the negative supply. The ADA4841-1/ ADA4841-2 can drive up to 20 pF of capacitive load with minimal peaking.
The ADA4841-1/ADA4841-2 provide the performance required to efficiently support emerging 16-bit to 18-bit ADCs and are ideal for portable instrumentation, high channel count, industrial measurement, and medical applications. The ADA4841-1/ ADA4841-2 are ideally suited to drive the AD7685/AD7686, 16-bit PulSAR ADCs.
The ADA4841-1/ADA4841-2 packages feature Pb-free lead finish. The amplifiers are rated to work over the industrial temperature range (−40°C to +125°C).
