The ADA4841-1YRJZ-R7 is a unity gain stable, low noiseand distortion, rail-to-rail output amplifier that has a quiescentcurrent of 1.5 mA maximum. In spite of its low powerconsumption, this amplifier offers low wideband voltagenoise 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 atlower frequencies, the amplifier has low 1/f noise of 7 nV/√Hzand 13 pA/√Hz at 10 Hz.
The ADA4841-1YRJZ-R7 output can swing to less than50 mV of either rail. The input common-mode voltage rangeextends down to the negative supply. The ADA4841-1YRJZ-R7 can drive up to 10 pF of capacitive load withminimal peaking.
The ADA4841-1YRJZ-R7 provides the performance requiredto efficiently support emerging 16-bit to 18-bit ADCs and is ideal for portable instrumentation, high channel count, industrialmeasurement, and medical applications. The ADA4841-1YRJZ-R7 is ideally suited to drive the AD7685/AD7686,16-bit PulSAR ADCs.
The ADA4841-1YRJZ-R7 package features RoHS compliantlead finishes. The amplifier is rated to work over theindustrial temperature range (−40°C to +125°C).
