ACS712ELCTR-05B-T
Overview
The ACS712ELCTR-05B-T is a fully integrated, Hall-effect based linear current sensor designed for AC or DC current sensing in low-power applications. It provides a ratiometric analog output voltage that varies linearly with the sensed current, typically used in systems requiring up to 5A of bidirectional measurement. The device features a low-resistance integrated copper conduction path located near the surface of the die, providing internal electrical isolation.
Why Choose This Part
This sensor offers 1.5 percent typical accuracy and 80kHz bandwidth in a compact SOIC-8 package. The integrated Hall effect technology provides inherent electrical isolation between the high-current path and the low-voltage electronics, eliminating the need for expensive optoisolators. Its low 1.2 mOhm internal conductor resistance minimizes power loss and thermal dissipation during operation.
Applications
Key Specifications
Getting Started
To evaluate this sensor, connect the conduction pins in series with the load and provide a stable 4.5V to 5.5V Vcc supply. The output voltage (VOUT) will be centered at Vcc/2 (2.5V nominal) for zero current; use an ADC-equipped microcontroller like an Arduino or STM32 to sample the analog signal. For optimal performance, include a 0.1 uF decoupling capacitor on the Vcc pin and a filter capacitor on the FILTER pin to adjust the device bandwidth.
