## Description

Compact solution for amplifying very small signals, useful in measurements and sensors where noise can affect accuracy. Operates at 3-12VDC, adjustable gain 1.5-1000x with adjustable zero, offers low offset and high common mode rejection for clean signal, includes negative voltage output for flexibility in circuits.
The AD620 Microvolt amplifier module is an optimized solution for amplifying low voltage signals. It improves input signals in the presence of noise and reduces the need for external components. Due to its ability to amplify small signals and its high resistance to noise, it is ideal for applications that require high quality signal processing.
It can amplify voltages in the uV, mV range at a magnification of 1.5-10000 times, adjustable. High precision, low offset, superior linearity. Adjustable zero to improve accuracy. It can be used to amplify AC and DC signals. Using the module requires a solid electronic base.
The module offers negative voltage output through the 7660A (-Vin) chip.
