The Allegro® ACS709 current sensor IC provides economical and precise means for current sensing applications in industrial, automotive, commercial, and communications systems. The device is offered in a small footprint surface mount package that allows easy implementation in customer applications. The ACS709 consists of a precision linear Hall sensor integrated circuit with a copper conduction path located near the surface of the silicon die. Applied current flows through the copper conduction path, and the analog output voltage from the Hall sensor IC linearly tracks the magnetic field generated by the applied current.
Even more, the datasheet contains info things like primary current signal, temperature, noise, thermal resistance, offset, current, resistance, external capacitor, characteristic symbol, signal, thermally enhanced package, product, and response.
