INA220AIDGST

产品概述

The INA220AIDGST is a low/high-side zero-drift bi-directional I²C out Current Shunt and Power Monitor with a two-wire interface. The INA220 monitors both shunt drop and supply voltage. A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes. An additional multiplying register calculates power in watts. The two-wire interface features 16 programmable addresses. The separate shunt input on the monitor allows it to be used in systems with low-side sensing. The monitor senses across shunts on buses that can vary from 0 to 26V, useful for low-side sensing or CPU power supplies. This monitor draws a maximum of 1mA of supply current.
