ACS712ELCTR-20A
Overview
The ACS712ELCTR-20A is a fully integrated, Hall-effect based linear current sensor IC designed for AC or DC current sensing in industrial, commercial, and communications systems. It provides a ratiometric analog output voltage that varies linearly with the sensed current up to 20A, featuring 2.1kVRMS isolation and a low-resistance internal conductor path.
Why Choose This Part
The device features a 5us output rise time and a low-noise analog signal path for high-speed applications. Its SOIC-8 package integrates the primary conductor, eliminating the need for external sense resistors and reducing PCB footprint while providing electrical isolation.
Applications
Key Specifications
Getting Started
Engineers should interface the analog output to a 5V ADC input on a microcontroller, ensuring the ratiometric output is compensated for supply voltage fluctuations. For prototyping, several breakout boards are available from suppliers like Adafruit or SparkFun that simplify the high-current terminal connections.
