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 packages feature RoHS compliant  
lead finishes. The amplifiers are rated to work over the  
industrial temperature range (−40°C to +125°C).

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/  
ADA4841-2 are ideally suited to drive the AD7685/AD7686,  
16-bit PulSAR ADCs.
