Low Cost Low Power Instrumentation Amplifier AD620 FEATURES CONNECTION DIAGRAM Weigh scales ECG and medical instrumentation Transducer interface Data acquisition systems Industrial process controls Battery-powered and portable equipment –IN 2 7 +VS +IN 3 6 –VS 4 AD620 RG OUTPUT 5 REF Figure 1. 8-Lead PDIP (N), CERDIP (Q), and SOIC (R) Packages PRODUCT 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 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, 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 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 Superϐeta processing in the input stage. The AD620 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 AD620 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. 30,000 TOTAL ERROR, PPM OF FULL SCALE Comment Better specs at lower price Dual channel or differential out Low power, wide input range JFET input Best gain accuracy +2 precision op amps or differential out Ultra low noise 8 TOP VIEW Table 1.
