Description:
The AD620 voltage amplifier is high Precision μV/mV Voltage Amplifier Small Signal Instrumentation Amplifier AD620 Transmitter. Using AD620 as the main amplifier, can amplify uV, mV voltage. Magnification 1.5-10000 magnification, adjustable. High precision, low offset, better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification. This AD620 voltage amplifier can adjust microvolts, millivolt, compared to LM358 amplification accuracy, better linearity, the maximum voltage output range of ± 10V. Magnification up to 1000 times, only through a potentiometer can be adjusted. Adjustable zero through the zero potentiometer to adjust the zero, improve accuracy, there will be no zero drift phenomenon to meet customer needs. With negative voltage output, the module uses 7660A chip output negative voltage (-Vin), can be provided to the customer to drive other dual power load.
Parameters:
Input voltage: DC3-12V
Magnification: 1.5-1000 times adjustable, zero adjustable
Signal input voltage: 100uV - 300mV
Signal output range: ± (Vin-2V)
Negative voltage output: higher than -Vin. As the negative voltage chip output resistance problem, the actual output is higher than -Vin, the greater the load power, the greater the negative voltage drop.
Offset voltage: 50V.
Input bias current: 1.0nA (max).
Common mode rejection ratio: 100 dB
Offset voltage drift: 0.6V / ° (maximum).
Stability: 2V / month maximum
Size: 32 * 22mm
Package included:
2 x AD620 High Precision Voltage Amplifiers
