Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service. 

Introduction

The ACS724 is a high-performance Hall-effect current sensor capable of measuring both alternating current (A_C) and direct current (D_C) more effectively. It is widely used in industrial, consumer, and communication devices. The ACS724 series integrates a high-precision, low-noise linear Hall circuit and a low-impedance main current loop conductor. When the sampled current flows through the main current loop, the magnetic field it generates induces a corresponding electrical signal in the Hall circuit. This signal is processed and output as a voltage signal, making the product's output strictly proportional to the measured current value. The linear Hall circuit is manufactured using advanced BCDMOS technology and includes a high-sensitivity Hall sensor, Hall signal preamplifier, high-precision Hall temperature compensation unit, oscillator dynamic offset cancellation circuit, and amplifier output module. In the absence of a magnetic field, the sensor's static output is 50%V. Under a 5V supply voltage, the sensor's static output varies linearly with the magnetic field between 0.2V and 48V, with a linearity of up to 0.4%. The dynamic offset cancellation circuit integrated into the ACS724 ensures that the sensor's sensitivity is unaffected by external pressure and package stress. The ACS724 is available in an SOP8 package, with an operating temperature range of -40 to 150°C, and complies with RoHS standards.
