Description
The AD620 is a low cost, high accuracy instrumentation amplifier which
requires only one external resistor to set gains of 1 to 1000. Furthermore,
the AD620 features 8-pin 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 AD620, with its high accuracy of 40 ppm maximum nonlinearity, low offset
voltage of 50 mV max and offset drift of 0.6 mV/ degrees C max, is ideal for
use in precision data acquisition systems, such as weigh scales and
transducer interfaces. Further-ECG more, the low noise, low input bias
current, and low power of the AD620 make it well suited for medical
applications such as ECG and noninvasive blood pressure monitors.
