AD620 Amplifier IC?is a low-cost, high-accuracy instrumentation amplifier that requires only one external resistor to set gains of 1 to 10,000. Furthermore, the AD620 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 SMD, with its high accuracy of 40 ppm maximum nonlinearity, the low offset voltage of 50 ?V max, and offset drift of 0.6 ?V/?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 AD620 SMD 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?eta processing in the input stage. The AD620 SMD works well as a preamplifier due to its low input voltage noise of 9 nV/?Hz at 1 kHz, 0.28 ?V p-p in the 0.1 Hz to 10 Hz band, and 0.1 pA/?Hz input current noise. Also, the AD620 SMD is well suited for multiplexed applications with its settling time of 15 ?s to 0.01%, and its cost is low enough to enable designs with one in-amp per channel.
