Voltage Amplifier Module Microvolt/Millivolt Small Signal Instrumentation Transmitter AD620

Feature:1. The input range is wide. This product uses AD620 to amplify, which can amplify microvolts and millivolts. Possess higher amplification accuracy and better linearity than the LM358 on the market, and the maximum voltage output range is ±9V2. A potentiometer is used to amplify the input signal, the magnification is up to 1000 times, and can be adjusted only through a potentiometer3. The zero point can be adjusted by the zero‑adjusting potentiometer to improve the accuracy, and there will be no zero‑point drift to meet customer needs4. The module uses 7660A negative pressure chip to output negative pressure (-Vin), which can be provided to customers to drive other dual power loads5. Mini type, size is 32 x 22mm, there are 4 3mm positioning holes evenly distributed around, 2.54mm standard spacing on both sidesSpecification:Item Type: Voltage Amplifier ModuleMaterial: ResinModel: AD620Input Voltage: DC 3-11VMagnification: 1.5-1000 Times adjustable, zero point adjustableCommon Mode Rejection Ratio: 100dBInput Bias Current: 1.0nA (maximum)Negative Pressure Output: Greater than -Vin. Due to the output internal resistance of the negative pressure chip, the actual output is greater than -Vin, and the greater the load power, the greater the negative pressure dropSize: Approx. 32 x 22mm / 1.3 x 0.9inPositioning Holes: Approx. 3mm / 0.12inStandard Spacing: Approx. 2.54mm / 0.1in.Package List:1 x Voltage Amplifier Module2 x Pin HeaderNote:+S: Signal input terminal, ‑S: Signal input negative terminal(can be connected to GND), Vout signal output, V‑ output a voltage of ‑Vin (for sensor power supply). Signal input, signal output, power input, the 3 signals must share the ground.
