The ADA4940-1ARZ is a low noise low distortion fully Differential Amplifier with very low power consumption. It is an ideal choice for driving low power, high resolution, high performance SAR and sigma-delta (Σ-Δ) analog-to-digital converters (ADCs) with resolutions up to 16 bits from DC to 1MHz on only 1.25mA of quiescent current. The adjustable level of the output common-mode voltage allows the ADA4940-1 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. With the ADA4940-1, differential gain configurations are easily realized with a simple external feedback network of four resistors determining the closed-loop gain of the amplifier.
