AD8475 datasheet

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-to
differential conversion along with input overvoltage protection. Power dissipation on a single 5V supply is only 16mW. The AD8475 is a simple to use, fully integrated precision gain block, designed to process signal levels of up to ±10 V on a single supply. It provides a complete interface to make industrial level signals directly compatible with the differential input ranges of low voltage high performance 16-bit or 18-bit single-supply successive approximation (SAR)analog-to-digital converters (ADCs).

6. VOCM pin adjusts output common-mode voltage
7. Robust overvoltage protection up to ±15 V (VS = +5 V)
8. Single supply: 3 V to 10 V
9. Dual supplies: ±1.5 V to ±5 V
10. High performance
11. Suited for driving 18-bit converters up to 4 MSPS
12. 10 nV/√Hz output noise
13. 3 ppm/°C gain drift
14. 500 μV maximum output offset
15. 50 V/μs slew rate
16. Low power: 3.2 mA supply current

Applications

1. ADC drivers
2. Differential instrumentation amplifier building blocks
3. Single-ended-to-differential converters
