                                                ACS725LLCTR-20AB-T Overview
The current sensors are put into 8-SOIC (0.154, 3.90mm Width) packages for safety protection.  In order to protect the devices from damage, these current sensors are packaged in the Tape & Reel (TR). Current sensors should supply no more current than 14mA. Current sensors terminate at 8. There are 8 pins in this current sensor. While working, these sensors can supply a voltage of 3.3V. It is recommended that current sensors supply a voltage of 3V as their minimum voltage. It is important that current sensors do not supply voltages exceeding 3.6V. As these components operate, their current should be 10mA.
