APPLICATIONS Low power, low noise signal processing Battery-powered instrumentation 16-bit PulSAR® ADC drivers GENERAL DESCRIPTION The ADA4841-2KGD 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 ADA4841-2KGD is ideally suited to drive the AD7685/AD7686, 16-bit PulSAR ADCs. Rev. 0 –30 –40 VS = ±5V G = +1 –50 –60 –70 2V p-p THIRD –80 –90 –100 2V p-p SECOND 13370-002 The ADA4841-2KGD output can swing to less than 50 mV of either rail. The input common-mode voltage range extends down to the negative supply. The ADA4841-2KGD can drive up to 10 pF of capacitive load with minimal peaking. Additional application and technical information can be found in the ADA4841-2 data sheet. HARMONIC DISTORTION (dBc) The ADA4841-2KGD is a unity-gain stable, low noise and distortion, rail-to-rail output amplifier that has a quiescent current of 1.5 mA maximum. Its low power consumption notwithstanding, 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. –110 –120 0.01 0.1 FREQUENCY (MHz) 1 Figure 2.
