The ADA4841-1/ ADA4841-2 are ideally suited to drive the AD7685/AD7686, 16-bit PulSAR ADCs. –30 –40 VS = ±5V G = +1 –50 –60 –70 2V p-p THIRD –80 –90 –100 2V p-p SECOND –110 –120 0.01 05614-048 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 packages feature Pb-free lead finish. The amplifiers are rated to work over the industrial temperature range (−40°C to +125°C). HARMONIC DISTORTION (dBc) 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. 0.1 1 FREQUENCY (MHz) Figure 4. Harmonic Distortion Rev.
