Description

The A7840 isolation amplifier provides accurate signal isolation with high common-mode transient immunity. It is ideal for use in systems where input signals need to be isolated from the output to protect sensitive components and prevent ground loops. The IC typically integrates a transformer or optical isolation mechanism to achieve this isolation.

Features

  • High Voltage Isolation: Provides isolation of up to several kilovolts between input and output.
  • High Common-Mode Rejection Ratio (CMRR): Ensures that the common-mode noise is effectively rejected, providing a clean signal at the output.
  • Wide Input Voltage Range: Capable of accepting a broad range of input voltages, suitable for various applications.
  • Low Offset and Drift: Ensures stable and accurate signal transmission over temperature and time.
  • High Bandwidth: Capable of transmitting signals with high frequency, suitable for high-speed applications.
  • Low Power Consumption: Designed to operate with minimal power, enhancing efficiency in power-sensitive applications.

Specifications

  • Isolation Voltage: Typically in the range of 2.5 kV to 7.5 kV, depending on the model.
  • Input Voltage Range: Varies by model but generally supports ±10V or 0-5V inputs.
  • Output Voltage Range: Generally matches the input range with some amplification or attenuation possible.
  • Bandwidth: Usually in the range of several kHz to MHz, depending on the application.
  • Power Supply Voltage: Operates at a supply voltage, commonly around ±15V or a single +5V.
  • Power Consumption: Typically low, around 30 mW to 150 mW.
  • Temperature Range: Operating temperature ranges typically from -40°C to +85°C.
  • Package Type: Commonly available in surface-mount packages like SOIC or DIP for easy integration into circuits.

Applications

  • Medical Equipment: For isolating patient-connected devices from monitoring or control systems.
  • Industrial Automation: In motor control systems, sensors, and data acquisition systems where high voltage transients may be present.
  • Power Monitoring: For isolating high-voltage power lines from control circuits.
  • Data Acquisition Systems: Ensures accurate signal measurement without ground loop interference.
