ACS712ELCTR-20A-T
Overview
The ACS712ELCTR-20A-T 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 features a low-resistance 1.2 mOhm internal conductor and provides a ratiometric analog output voltage that varies linearly with the sensed current up to 20A.
Why Choose This Part
The device offers 2.4 kVRMS minimum galvanic isolation, eliminating the need for expensive optoisolators in high-side sensing applications. It provides a fast 5us output rise time and 80 kHz bandwidth with a low-noise analog signal path and a user-adjustable filter pin to optimize signal-to-noise ratios.
Applications
Key Specifications
Getting Started
Connect the current path to pins 1-2 and 3-4, then monitor the VOUT pin using a 5V ADC on your microcontroller. To reduce noise, add a capacitor from the FILTER pin to ground as specified in the datasheet to adjust the bandwidth for your specific application requirements.
