ACS764 Overview
The Allegro™ ACS764 fully integrated Hall-effect current sensor IC is designed for applications that require digital current sensing and reporting through an I2C™ bus. Allegro factory programming of the offset and gain, including the temperature coefficients, stabilizes the offset and gain over the operating temperature range. This programming greatly reduces the device total error, typically less than 2% over the...
ACS764 Key Features
- Fully integrated current sensor IC in a pact QSOP package eliminates the need for shunt resistors
