What is it?

This current sensor offers precise and stable current measurements in magnetically noisy environments, featuring differential sensing for common-mode rejection, galvanic isolation, and a wide operating temperature range. The module is based on the ACS724 IC from Allegro Microsystems and operates from a single 5V supply.

Why did you make it?

Easy and precise current measurements using integrated hall-effect sensor.

What makes it special?

• bidirectional current sensing capability of ±5A
• operates from single 5V power supply
• differential Hall sensing rejects common-mode fields
• high-bandwidth 120 kHz analog output
• integrated digital temperature compensation for near-closed loop accuracy
• bandwidth limiting option enables better resolution at lower frequencies
