AD8475 - Fully Differential Funnel Amplifier

Description

The AD8475 is a fully differential, attenuating amplifier with integrated precision gain resistors.

It provides precision attenuation (by 0.4 or 0.8), common-mode level shifting, and single-ended-todifferential conversion along with input overvoltage protection.

Features

  • Precision attenuation: G = 0.4, G = 0.8 Fully differential or single-ended input/output Differential output designed to drive precision ADCs Drives switched capacitor and Σ-Δ ADCs Rail-to-rail output VOCM pin adjusts output common-mode voltage Robust overvoltage protection up to ±15 V (VS = +5 V) Single supply: 3 V to 10 V Dual supplies: ±1.5 V to ±5 V High performance Suited for driving 18-bit converters up to 4 MSPS 10 nV/√Hz output noise 3 ppm/°C gain drift 500 μV maximum output offset 50 V/μ.
