ADA4940-1ARZ

ADA4940-1 is an ultralow power, low distortion, fully differential ADC driver. It is an ideal choice for driving low power, high resolution, high performance SAR and Σ-Δ analogue-to-digital converters (ADCs) with resolution up to 16bits from dc to 1MHz on only 1.25mA of quiescent current. The adjustable level of the output common mode voltage allows the device to match the input common-mode voltage of multiple ADCs. The internal common-mode feedback loop provides exceptional output balance, as well as suppression of even-order harmonic distortion products. It is widely used in application such as low power PulSAR®/SAR ADC drivers, single-ended-to-differential conversion, differential buffers, line drivers, medical imaging, industrial process controls, portable electronics etc.
