## Description

Using AD620 as the main amplifier, can amplify uV, mV voltage. Amplification: adjustable 1.5-10000 times. High precision, low offset, better linearity. Adjustable zero to improve accuracy. Can be used for AC, DC signal amplification.  Parameter: Input voltage range: DC 3-11V Amplification: adjustable 1.5-1000 times, adjustable zero Signal input voltage range: 100&#x3BC;V-300mV Signal output range: &#xB1; (Vin-2V) Negative voltage output: > -Vin, for the output resistance of negative voltage chip, the actual output is greater than -Vin, the greater the load power, the greater the negative voltage drop. Offset voltage: 50&#x3BC;V Input bias current: 1.0nA (Max) Common mode rejection ratio: 100dB Offset voltage drift: 0.6&#x3BC;V/&#x2103; (Max) Dimension: 32x22mm  Package Including: 1x Signal Amplifier Module

## Features

- Signal Amplifer Input voltage range is DC 3-11V, signal input voltage range 100μV-300mV, signal output range ± (Vin-2V).
- The signal amplifer adopts potentiometer to amplify the input signal, max amplification can be 1000 times, amplification could be easily adjusted by the potentiometer.
- It uses AD 620 amplifier, can amplify microvolt, milivolt, the max output voltage range is ± 9V, can offer higher amplification precision than LM358.
- DROK voltage amplifer module adopts 7660A negative voltage chip to output negative voltage(-Vin), can be used to drive other dual power load.
- It can not only improve the accuracy, but also can avoid the zero drift phenomenon by using the zero potentiometer to adjust the zero. NOTE: the input voltage please don't exceed 11V, or the module might be burned.
