3 Description
The INA220 is a current shunt and power monitor with an I2C- or SMBUS-patible interface. The INA220 monitors both shunt drop and supply voltage. A programmable calibration value, bined with an internal multiplier, enables direct readouts in amperes. An additional multiplying register calculates power in watts. The I2C- or SMBUS-patible interface features
16 programmable addresses. The separate shunt input on the INA220 allows it to be used in systems with low-side sensing.
The INA220 is available in two grades: A and B. The B...
