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. In spite of 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 provides the performance required to efficiently support emerging 16-bit to 18-bit ADCs and is ideal for portable instrumentation, high channel count, industrial measurement, and medical applications. The ADA4841-1 is ideally suited to drive theAD7685/AD7686, 16-bit PulSAR ADCs.The ADA4841-1 package features RoHS compliant lead finishes. The amplifier is rated to work over the industrial temperature range (−40°C to +125°C).ApplicationsLow power, low noise signal processingBattery-powered instrumentation16-bit PulSAR®ADC drivers
