Description:
This is Low Power, Wide Supply Range, Low Cost Unity-Gain Difference Amplifier.
The AD8276 / AD8277 are general-purpose, unity-gain difference amplifiers intended for precision signal conditioning in power critical applications that require both high performance and low power. They provide exceptional common-mode rejection ratio(86 dB) and high bandwidth while amplifying signals well beyond the supply rails. The on-chip resistors are laser-trimmed for excellent gain accuracy and high CMRR. They also have extremely low gain drift vs. temperature.
The common-mode range of the amplifiers extends to almost double the supply voltage, making these amplifiers ideal for single supply applications that require a high common-mode voltage range. The internal resistors and ESD circuitry at the inputs also provide overvoltage protection to the op amps.
Features:
1. Wide input range beyond supplies
2. Rugged input overvoltage protection
3. Low supply current: 200 μA maximum per channel
4. Low power dissipation: 0.5 mW at VS= 2.5 V
5. Bandwidth: 550 kHz
6. CMRR: 86 dB minimum, dc to 10 kHz
7. Low offset voltage drift: ±2 μV/°C maximum (B Grade)
8. Low gain drift: 1 ppm/°C maximum (B Grade)
9. Enhanced slew rate: 1.1 V/μs
10. Wide power supply range:
11. Single supply: 2 V to 36 V
12. Dual supplies: ±2 V to ±18 V
Applications:
1. Voltage measurement and monitoring
2. Current measurement and monitoring
3. Differential output instrumentation amplifier
4. Portable, battery-powered equipment
5. Test and measurement
