AD620ARZ | ANALOG DEVICES

Instrumentation amplifier, AD620ARZ, ANALOG DEVICES

The AD620ARZ is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the AD620ARZ features 8-lead SOIC and DIP packaging that is smaller than discrete designs and offers lower power (only 1.3 mA max supply current), making it a good fit for battery powered, portable (or remote) applications. The AD620ARZ, with its high accuracy of 40 ppm maximum nonlinearity, low offset voltage of 50 µV max, and offset drift of 0.6 µV/°C max, is ideal for use in precision data acquisition systems, such as weight scales and transducer interfaces. Furthermore, the low noise, low input bias current, and low power of the AD620ARZ make it well suited for medical applications such as ECG and noninvasive blood pressure monitors.
