31Description
32-----------
33
34The INA219 is a high-side current shunt and power monitor with an I2C
35interface. The INA219 monitors both shunt drop and supply voltage, with
36programmable conversion times and filtering.
37
Guenter Roeckdc92cd02012-05-12 11:33:11 -070038The INA220 is a high or low side current shunt and power monitor with an I2C
39interface. The INA220 monitors both shunt drop and supply voltage.
