High-precision power monitoring IC with I2C interface.
The "CAD2726" is a current shunt and power monitor IC equipped with an I2C interface. It monitors both the shunt voltage drop and the bus supply voltage. This device can directly read current in amperes and power in watts by combining programmable calibration values, conversion time, and averaging options with an internal multiplier. The I2C interface supports up to 16 types of programmable addresses.
