Features Wide input range with AD620 amplification allows for amplification of microvolts and millivolts with higher accuracy and linearity than LM358, providing precise signal amplification. Potentiometer-based signal amplification with up to 1000 times magnification, easily adjustable to meet specific signal amplification needs with precision. Null point adjustment through potentiometer for improved accuracy and no null-point drift, ensuring stable and reliable performance to meet customer requirements. Negative pressure output module using 7660A negative pressure chip for -VIN output to drive dual power loads, offering versatile functionality for various applications. Compact design with 4 3MM positioning holes, 2.54MM standard spacing on both sides, and ±10V maximum voltage output range, providing a versatile and convenient solution for voltage amplification needs. Specification: Item Type: Millivolt Voltage Amplifier Input Voltage: 3-12VDC Magnification: 1.5-1000 Times Adjustable, the Null Point Can Be Adjusted the Same As the Lower One Signal Input Voltage: 100UV--300MV Signal Output Range: ± (VIN-2V) Negative Pressure Output: Greater Than -VIN. Due to the Output Internal Resistance of the Negative Pressure Chip, the Actual Output is Greater Than -VIN, the Greater the Load Power, the Greater the Negative Pressure Drop Offset Voltage: 50MV Input Bias Current: 1.0NA (Maximum) Common Mode Rejection Ratio: 100DB Offset Voltage Drift: 0.6MV / C (Maximum) Stable Time: 2MV / Month Maximum Simultaneous Interpretation Set Size: Approx. 32 x 22mm / 1.3 x 0.9in Package List: 1 x Millivolt Voltage Amplifier Note: The use of the module requires a certain electronic basic.
