• Bandwidth adjustable via FILTER pin.
• 5 µs output rise time for rapid response to changing current.
• Compact SOIC-8 package for easy PCB integration.
• 2.1 kV RMS minimum isolation voltage between primary current path and signal pins.
• Operates on a single 5V supply.
• Output sensitivity ranges from 66 to 185 mV/A depending on version.
• Analog voltage output proportional to both AC and DC current.
• Factory-trimmed for offset accuracy and low drift.
• Excellent stability and near-zero magnetic hysteresis.
• Ratiometric output—scales proportionally with supply voltage for consistent performance.

DESCRIPTION:

• The ACS712-5AMS-CURRENT-W is a Hall-effect based linear current sensor module, designed for accurate measurement of AC and DC currents up to ±5A.
• Built around the ACS712ELC-05B sensor IC, this module integrates precision analog circuitry for stable and noise-free performance.
• The Hall-effect sensing element detects the magnetic field produced by current flow, converting it into a proportional analog voltage output.
• The output can be easily read by the analog-to-digital converter (ADC) of a microcontroller such as Arduino, ESP32, or Raspberry Pi Pico.
• The sensor operates from a single 5V supply and outputs a centered voltage (~2.5V at zero current), which increases or decreases linearly with the current direction.
• The FILTER pin allows users to set bandwidth via an external capacitor, enabling flexibility for noise-sensitive or high-speed applications.
• The compact module simplifies integration, making it ideal for power monitoring, current control, and protection systems.
