ACS712ELCTR-20A-T

The Allegro MicroSystems current sensor easily measure the flow of current in an electric circuit. The ACS712 is provided in a small, surface mount SOIC8 package. The leadframe is plated with 100% matte tin, which is compatible with standard lead (Pb) free printed circuit board assembly processes. This device has a minimum operating supply voltage of 4.5 V and a maximum of 5.5 V. It has an operating frequency of 80 kHz. This part has a minimum operating temperature of -40 °C and a maximum of 85 °C. This device comes in tape and reel packaging during shipment.
