ADA4841-2YRMZ-RL

ADA4841-2 is a low power, unity gain stable, low noise and distortion, rail-to-rail output amplifier that has a quiescent current of 1.5mA maximum. In spite of their low power consumption, this amplifier offers low wideband voltage noise performance of 2.1nV/√Hz and 1.4pA/√Hz current noise, along with excellent spurious-free dynamic range (SFDR) of -105dBc at 100KHz. To maintain a low noise environment at lower frequencies, the amplifiers have low 1/f noise of 7nV/√Hz and 13pA/√Hz at 10Hz. ADA4841-2 output can swing to less than 50mV of either rail. The input common-mode voltage range extends down to the negative supply. The ADA4841-2 can drive up to 10pF of capacitive load with minimal peaking. Application includes low power, low noise signal processing, battery-powered instrumentation, 16bit PulSAR® ADC drivers.
