The AD8476ARMZ is a Fully Differential Amplifier and ADC Driver with integrated gain resistors for unity gain. It is an ideal choice for driving low power, high performance ADCs as a single-ended-to-differential or differential-to-differential amplifier. It provides a precision gain of 1, common-mode level shifting, low temperature drift and rail-to-rail outputs for maximum dynamic range. The AD8476 works well with SAR, Σ-Δ and pipeline converters. The high current output stage of the part allows it to drive the switched capacitor front-end circuits of many ADCs with minimal error. Unlike many differential drivers, the AD8476 is a high precision amplifier. With 200µV maximum output offset, 39nV/√Hz noise and -102dB THD + N at 10kHz, the AD8476 pairs well with low power, high accuracy converters. Considering its low power consumption and high precision, the slew-enhanced AD8476 has excellent speed, settling to 16-bit precision for 250kSPS acquisition times.
