Function:
1 The wide input range amplified using the AD620 can amplify microbolts and mifolts with higher precision and straightness than the LM358 on the market.
2. Potentiometer is used to amplify the input signal, the magnification is up to 1000 times and can be adjusted only through the potentiometer.
3 Use the null point adjustment potentiometer to adjust the null point to improve accuracy. No null point drift phenomenon to meet the needs of customers.
4 It has a negative pressure output module and uses a 7660A negative pressure chip to output negative pressure (‑VIN). It can be provided to customers to drive other dual power loads.
5 Small size, 3MM positioning holes are placed equally with 4 positioning, 2.54MM standard intervals on both sides, and the maximum voltage output range is ±10V.
Specifications:
Item Type: Millivolt Voltage Amplifier
Input Voltage: 3 - 12 VDC
