Description

? AD620 Instrumentation Amplifier Module Introduction:

The AD620 is a low-cost, high-accuracy instrumentation amplifier that requires only one external resistor to set the gain over a gain range of 1 to 10,000. Ideal for battery-powered and portable (or remote) applications. With high accuracy, low offset voltage, and low offset drift, the AD620 is ideal for precision data acquisition systems such as electronic scales and sensor interfaces. It also features low noise, low input bias current, and low power consumption, making it ideal for applications such as ECGs and non-invasive blood pressure monitors. The module has a fixed voltage output. To meet the needs of customers, our store will distribute shielding covers + sliding change without welding during delivery. Users can choose according to their own needs.
