Description
The AD8476 is a very low power, fully differential precision amplifier 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.

1. Very low power : 330 μA supply current
2. Extremely low harmonic distortion
(1) 126 HD2 at 10 kHz
(2) 128 HD3 at 10 kHz
3. Fully differential or single-ended inputs/outputs
4. Differential output designed to drive precision ADCs
(1) Drives switched capacitor and Σ-Δ ADCs
(2) Rail-to-rail outputs
5. VOCM pin adjusts output common mode
6. Robust overvoltage up to18 V beyond supplies
7. High performance
(1) Suitable for driving 16-bit converter up to 250 kSPS
(2) 39 nV/√Hz output noise
(3) 1 ppm/°C gain drift maximum
(4) 200 μV maximum output offset
(5) 10 V/μs slew rate
(5) 6 MHz bandwidth
8. Single supply: 3 V to 18 V
9. Dual supplies: ±1.5 V to ±9 V
