AD8476 is a low power, unity gain, fully differential amplifier and ADC driver. The device features a supply current of 330μA, can drive high precision ADCs, and can be used with switched capacitor and Σ-Δ ADCs. AD8476 has a 5MHz bandwidth, 10V/μs slew rate, 39nV/√Hz output noise, and 200μV maximum output offset.
The AD8476 is a low‑power, fully differential precision amplifier with integrated gain resistors for unity gain. It is designed to drive high‑performance ADCs, offering rail‑to‑rail outputs, over‑voltage protection up to +23 V, and a supply current as low as 330 pA.
