Description

The AD623 is a low-power, high-precision instrumentation amplifier with a fixed gain setting that can be adjusted with a single external resistor. The device features a high common-mode rejection ratio (CMRR) and low offset voltage, which makes it suitable for amplifying small differential signals in the presence of noise.

Features

  • Low Power Consumption: Designed to operate with low power consumption, making it ideal for battery-operated and energy-efficient applications.
  • Precision Performance: Offers high accuracy with low offset voltage, low offset drift, and low noise, ensuring precise amplification of small signals.
  • Adjustable Gain: Gain can be set with a single external resistor. 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.
  • High Common-Mode Rejection Ratio (CMRR): Provides excellent CMRR, reducing noise and interference that can affect signal accuracy.
  • Wide Supply Voltage Range: Operates over a wide supply voltage range, typically from ±2.3V to ±18V.
  • Low Input Bias Current: Ensures high input impedance with minimal input bias currents, which is important for accurate signal measurement.
  • Low Noise: Designed to minimize noise, which is crucial for applications involving weak 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: Ideal for medical devices like ECG, EEG, and other biosignal measurement systems where high precision and low noise are required.
  • Data Acquisition Systems: Used for amplifying small signals from sensors and transducers in data acquisition systems.
  • Industrial Measurement: Suitable for precise signal measurement and conditioning in industrial applications such as process control.
  • Weighing Systems: Commonly employed in load cells and weighing systems for accurate differential signal amplification.
  • Precision Analog Signal Processing: Useful in any application where accurate analog signal processing is needed, such as in precision measurement and instrumentation.
