With functions of differential output and external adjustable gain

Worcester, Massachusetts- 亚博棋牌游戏Allegro MicroSystems, LLC has unveiled a new Allegro current sensor IC, the IC can be used for industrial, commercial and communication system of AC electric flu, is a kind of economical and practical, accurate solution.Allegro 'ACS726Is the first containing can be adjusted by external RC network gain and bandwidth of the differential current sensor IC back-end amplifier.The back-end amplifier is completely independent, can disconnect the power when not in order to reduce power consumption.The device fully differential output provides more excellent output bias drift and common mode noise resistance.

The device adopts the packaging design, to facilitate customers to use.Typical applications include motor control, load detection and management, switch power supply, and overcurrent fault protection.

This device has low accurate offset linear hall sensor circuit, and the copper current path near the surface of the wafer.Through the copper current path of current can generate can be integrated hall IC and translated into is proportional to the voltage of the induced magnetic field.Through the magnetic field near the hall sensor, optimizing the device accuracy.Accurate is proportional to the voltage stable by the chopper type low bias BiCMOS hall IC, the IC packaging accuracy after programming.

When used as electric measuring flu pathways through the main copper current path (from pins 1 to 6, 7 to 12) to the pin of the current increasing, the device to the positive difference output voltage (V)_OUTP- V_OUTN).The pathway of the internal resistance is 1.1 m Ω, usually has lower power consumption.

Pathway of terminal and sensor IC signal pin (pin 13 to 24) between the electrical insulation.This makes ACS726 current sensor IC can be used in high-end differential amplifier or other expensive insulation technology used in high current sensing applications.

ACS726 QSOP - 24 mounted with thin small surface encapsulation (suffix LF).Fog pin box with 100% of tin plating, can be compatible with standard lead-free PCB assembly process.Except the inversion method of using the current exemption from the intense heat of RoHS leaded solder ball, contains no lead inside the device.Device (not including BAE) has complete calibration in factory before shipment.
