JSMSEMI ACS712ELCTR-30A-T-JSM

The ACS712 is a high-performance Hall-effect current sensor capable of measuring AC or DC current with greater efficiency, widely used in industrial, consumer, and communications equipment. The ACS712 series integrates a high-precision, low-noise linear Hall circuit and a low-resistance primary current conductor. When the sampled current flows through the primary current path, the resulting magnetic field induces a corresponding electrical signal in the Hall circuit, which is processed by the signal conditioning circuitry to produce a voltage output that is strictly proportional to the measured current. The linear Hall circuit is fabricated using an advanced BCDMOS process and incorporates a high-sensitivity Hall sensor, Hall signal preamplifier, high-precision Hall temperature compensation unit, oscillator, dynamic offset cancellation circuit, and amplifier output stage. In the absence of a magnetic field, the quiescent output of the current sensor is 50% Vcc. With a 5V supply voltage, the sensor's quiescent output varies linearly with the magnetic field in the range of 0.2~4.8V, with a linearity of up to 0.4%. The dynamic offset cancellation circuit integrated in the ACS712 ensures that sensor sensitivity is unaffected by external stress and IC package stress. The ACS712 is available in an SOP8 package, operates over a temperature range of -40~150°C, and is RoHS compliant.
