Voltage Amplifier Module designed for precise microvolt and millivolt signal amplification. Ideal for instrumentation and small signal transmission applications requiring high accuracy and stability. Solves the need for reliable signal conditioning in sensitive measurement systems
Connect input signals to the S+ and S- terminals. Power the module with 3-11V DC. Adjust gain via potentiometer to achieve amplification up to 1000x. Use the zero-adjust potentiometer to minimize offset voltage. The V- output provides negative voltage for powering dual-supply components. Ensure all grounds are shared between input, output, and power connections for optimal performance
Specifications:
Item Type: Voltage Amplifier Module
Model: AD620
Input Voltage: DC 3-11V
Magnification: 1.5-1000 Times adjustable, zero point adjustable
Signal input voltage: 100uV-300mV
Unbalanced voltage: 50uV
Common Mode Rejection Ratio: 100dB
Input 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 drop
