LC ACS module 758 is one current detection module, mainly used ACS758-LCB current sensor.ACS758 is consist of precise low-offset linear Hall sensor circuit,and its copper current path is close to the wafer.
Through this copper current path applied current can be generated integrated hall IC sense and converted into a proportional magnetic field.through bringing the magnetic signal close to the Hall sensor,reach device accuracy optimization.

Introduced the hardware and instructions
board size: 40.5*28.4mm
Functions of the board:
VCC：positive of power supply（3-5.5V）
GND：negative of power supply
OU1：simulation signal output
OU2:OU1 following Op amp signal output
2.Instructions for use
Voltage output with current input relations: OU1 = VCC/2 + K * Ia
K is Sensor coefficient.Ia from IP+ flow IP-current
Linearity K :40mV/a
Detectable current(DC) range :Ia：±50A;
Output voltage formula: OU1=OU2=VCC/2+Ia*K=VCC/2+（40mV/A*Ia）
