INA220 Datasheet (Texas Instruments) - Bidirectional Current and Power Monitor

INA220, Bidirectional Current and Power Monitor

The INA220 is a current shunt and power monitor with an I2C- or SMBUS-compatible interface.

The INA220 monitors both shunt drop and supply voltage.

A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes.
