3 Description
The INA220 is a current shunt and power monitor
with an I
2C- 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. An additional multiplying register calculates
power in watts. The I
2C- or SMBUS-compatible
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 grade version has higher accuracy and higher
precision specifications.
The INA220 senses across shunts on buses that can
vary from 0 to 26 V, useful for low-side sensing or
CPU power supplies. The device uses a single 3- to
5.5-V supply, drawing a maximum of 1 mA of supply
current. The INA220 operates from –40°C to 125°C.
