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. In spite of 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
50 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 10 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/
16-bit PulSAR ADCs.
The ADA4841-1/ADA4841-2 packages feature RoHS compliant
lead finishes. The amplifiers are rated to work over the
industrial temperature range (40°C to +125°C).
