ADA4940-1 Low Distortion Fully Differential ADC Driver

The ADA4940-1/ADA4940-2 are low noise, low distortion fully differential amplifiers with very low power consumption. They are 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 .
