Allegro MicroSystems ACS712
The ACS712 outputs an analog signal, VOUT . The terminals of the conductive path are electrically isolated from the signal leads (pins 5 through 8). This allows the ACS712 to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.| Part No. | ACS712 |
