Microvolt Voltage Amplifier Signal Amplifier AD620 Instrument Amplifier Module

Sensor BlocksModule features1. High end instrument amplifier AD620 core, high , good linearity.2. Single power supply, support 3-5.5v power supply, easy to use!3. Integrated negative pressure generation module, dual power operation, easy to deal with negative signal / AC signal.4. Power input LC filter, pure and stable, ensure the stability of signal amplification.5. Built in negative voltage generation module, only single power supply can operate with dual power supply, simplifying the system design.6. Rail to rail output, the maximum output swing reaches + - VCC, far exceeding lm358 / AD620 and other core products (only to vcc-1.5v)7. The magnification is adjustable from 2 to 1000 times, which is suitable for different applications. The imported borders potentiometers have uniform resistance variation and stable resistance value, and the is more than 10 times higher than that of domestic potentiometers (poor potentiometers are often loose, open circuit and bouncing, resulting in large and small resistance, open circuit, etc., which can not guarantee the stability of magnification, so it is difficult to guarantee the accuracy).7. The module is simple, expandable, detailed and convenient for secondary development.main parameter Amplifier type: instrument amplifier AD620 coreInput range: 0.5Vcc (i.e. the voltage between S + / S - is less than half of the supply voltage.)Output range: + - VCC (rail to rail)Magnification: 2-1000 times adjustable.Power consumption: 150ua (typical) 650ua (maximum)Power supply: 3-5.5vGain accuracy: 0.35% (G > 2) 0.10% (g = 2)Input offset voltage: 100-200uvInput offset drift: 1uv / CMRR: 90dBGain bandwidth: 800KHz.PCB size: 40 * 23mm, with 4 m3 mounting holes
