Description

The AD620 is a high-performance, low-power instrumentation amplifier that provides precise differential amplification of small signals. It features a gain that can be adjusted with a single external resistor, making it highly configurable for different applications. The device is housed in an 8-pin DIP (Dual In-line Package), which makes it easy to integrate into various PCB designs.

Features

  • Low Power Consumption: The AD620 is designed to operate with low power consumption, making it suitable for battery-powered and low-power applications.
  • High Precision: Offers high accuracy with low offset voltage, low offset drift, and low noise, ensuring precise signal amplification.
  • Adjustable Gain: Gain can be set with a single external resistor, allowing for flexibility in different amplification needs. The gain is given by the formula Gain=1+49.4kΩRGtext{Gain} = 1 + frac{49.4 text{k}Omega}{R_{G}}, where RGR_{G} is the gain resistor.
  • Low Input Bias Current: Provides high input impedance with low input bias currents, which is crucial for accurate signal measurement.
  • Wide Supply Voltage Range: Operates over a wide supply voltage range, typically from ±2.3V to ±18V.
  • Low Noise: Designed to minimize noise, which is important for applications involving weak signals.
  • Common-Mode Rejection Ratio (CMRR): High CMRR, which helps reject noise and interference common to both input signals.

Specifications

  • Gain Range: 1 to 1000
  • Input Offset Voltage: 50 µV (max)
  • Input Offset Voltage Drift: 0.6 µV/°C (max)
  • Input Bias Current: 10 nA (typical)
  • Supply Voltage Range: ±2.3V to ±18V
  • Supply Current: 1.1 mA (typical)
  • Common-Mode Rejection Ratio (CMRR): 120 dB (typical)
  • Total Harmonic Distortion (THD): 0.002% (typical)
  • Operating Temperature Range: -40°C to +85°C
  • Package: 8-pin DIP

Applications

  • Medical Instrumentation: Used in medical devices such as ECG, EEG, and other biosignal measurement systems where precision and low noise are critical.
  • Data Acquisition Systems: Ideal for amplifying small signals from sensors and transducers in data acquisition and measurement systems.
  • Industrial Measurement: Applied in industrial systems for accurate signal measurement and conditioning in process control and monitoring.
  • Weighing Systems: Used in load cells and other weighing systems where precise differential amplification is required.
  • Precision Analog Signal Processing: Suitable for applications involving low-level analog signal processing where accuracy and low noise are important.
