Part Number : AD620
Function : Low Cost Low Power Instrumentation Amplifier
Package : SOIC 8 Pin Type
Maker : Analog Devices
Pinouts : 
Description :
The AD620 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the 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 AD620, 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 weigh scales and transducer interfaces.
Furthermore, the low noise, low input bias current, and low power of the make it well suited for medical applications, such as ECG and noninvasive blood pressure monitors.
The low input bias current of 1.0 nA max is made possible with the use of Superbeta processing in the input stage. The device works well as a preamplifier due to its low input voltage noise of
9 nV/√Hz at 1 kHz, 0.28 μV p-p in the 0.1 Hz to 10 Hz band, and 0.1 pA/√Hz input current noise. Also, the IC is well suited for multiplexed applications with its settling time of 15 μs to 0.01%, and its cost is low enough to enable designs with one in-amp per channel.
