AD620AN-DIP

The AD620 is a low cost, high accuracy instrumentation ampli-fier that requires only one external resistor to set gains of 1 to 1000. Furthermore, the AD620 features 8-lead SOIC and DIPpackaging that is smaller than discrete designs, and offers lowerpower (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 50μV max and offset drift of0.6 μV/°C max, is ideal for use in precision data acquisition systems, such as weigh scales and transducer interfaces. Fur-thermore, 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.The low input bias current of 1.0 nA max is made possible with the use of Super Beta processing in the input stage. The AD620 works well as a preamplifier due to its low input voltage noise of9 nV/√Hz at 1 kHz, 0.28μV p-p in the 0.1 Hz to 10 Hz band,0.1 pA/√Hz input current noise. Also, the AD620 is well suited for multiplexed applications with its settling time of 15μs to0.01% and its cost is low enough to enable designs with one in-amp per channel.
