Product Introduction
AD620 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set the gain, with a gain range of 1 to 10,000. In addition, the AD620 is available in 8-pin SOIC and DIP packages, offering a smaller footprint than discrete circuit designs and lower power consumption (maximum supply current of only 1.3 mA), making it ideal for battery-powered and portable (or remote) applications.
The AD620 features high accuracy (maximum nonlinearity of 40 ppm), low offset voltage (maximum 50 μV), and low offset drift (maximum 0.6 μV/°C), making it an ideal choice for precision data acquisition systems such as weigh scales and sensor interfaces. In addition, the AD620's low noise, low input bias current, and low power consumption make it well suited for medical applications such as ECG and noninvasive blood pressure monitors.
The input stage uses Superβeta processing to achieve a low input bias current of 1.0 nA maximum. The AD620 features low input voltage noise of 9 nV/√Hz at 1 kHz, 0.28 μV p-p noise over a 0.1 Hz to 10 Hz bandwidth, and input current noise of 0.1 pA/√Hz, making it an excellent choice as a preamplifier. The AD620 is also well suited for multiplexed applications, with a 0.01% settling time of 15 μs, and is low enough in cost to enable one instrumentation amplifier per channel designs.
