Product Introduction: High-Precision Microvolt/Millivolt Voltage Amplifier Module
Utilizing the AD620 as the primary amplifier, this module amplifies microvolt and millivolt-level voltages. The gain is adjustable from 1.5 to 10,000 times, delivering high precision, low offset, and improved linearity. Zero adjustment is provided to enhance accuracy. It supports amplification of both AC and DC signals.
This high-precision, low-offset AC/DC microvolt/millivolt voltage amplifier is suitable for amplifying small AC and DC signals, including microvolt and millivolt-level voltages. (Operation of this module requires foundational electronics knowledge. Customers without technical background are advised to exercise caution when purchasing.)
Voltage Amplifier Function Introduction
This voltage amplifier can amplify weak voltage signals to the required voltage level while minimizing signal distortion. Its precision reaches microvolt/millivolt levels, with specific parameters detailed below.
Voltage Amplifier Pinout
During use, the signal input, signal output, and power input must share a common ground.
+S serves as the signal input positive terminal, -S is the signal input negative terminal (can connect to grounded).
V- can output the Vin voltage (capable of powering sensors).

How to use voltage amplifier
Zero Adjustment Wiring Diagram: Before use, wire according to the diagram for zero adjustment. Short-circuit +S and -S, then adjust the trimming potentiometer until the output Vout reads 0V
Single-Ended Input Wiring Diagram: This wiring diagram is suitable for single-ended output signals from sensors, silicon photocells, etc.
Differential Input Wiring Diagram: This wiring diagram is suitable for sensors with differential outputs, such as pressure transducers and bridge circuits.
