ACS723LLCTR-10AB-T
Overview
The ACS723LLCTR-10AB-T is a high-accuracy, galvanically isolated Hall effect current sensor IC designed for bidirectional AC or DC measurements. It features integrated digital temperature compensation and an internal shield that provides high immunity to capacitive coupling from the current conductor. The device operates from a single 4.5V to 5.5V supply and outputs an analog voltage proportional to the primary current.
Why Choose This Part
The sensor offers an extremely low 0.65 mOhm primary conductor resistance, minimizing power dissipation and thermal load on the PCB. It includes a pin-selectable bandwidth of 80 kHz or 20 kHz to optimize for either response time (5 us) or noise performance. The galvanic isolation and 2.4 kVrms dielectric strength allow for safe, high-side current measurement without the need for external opto-isolators.
Applications
Key Specifications
Getting Started
To evaluate this sensor, provide a stable 5V supply to VCC and connect the current path to the IP+ and IP- pins. Use a decoupling capacitor on the VCC pin and a filter capacitor on the FILTER pin to select the desired bandwidth. The ratiometric output can be directly interfaced with a microcontroller ADC, with the 0A point typically centered at VCC/2.
