AD8475 is a fully differential attenuating amplifier with features including precise attenuation, fully differential or single-ended input/output, differential output design for driving precision ADCs, driving switch capacitors and Σ-Δ ADCs, rail-to-rail output, VOCM pin for adjusting output common mode voltage, overvoltage protection up to ±15 V (VS = +5 V), single or dual power supply operation, etc.
The AD8475 is a fully differential attenuating amplifier featuring integrated precision gain resistors that provide selectable attenuation of 0.4 or 0.8. It is designed to drive precision ADCs, including successive-approximation (SAR) and sigma-delta types, by providing common-mode level shifting and input overvoltage protection. The device supports both single-supply (3 V to 10 V) and dual-supply (±1.5 V to ±5 V) operation.
The device provides two selectable gain options of 0.4 and 0.8.
The maximum output offset voltage is 500 µV.
