Texas Instruments INA219AIDCNR INA219AIDCNR Current Sense Amplifier 1 SOT-23 8 Pins -25 °C 85

The INA219AIDCNR is a high-side Current Shunt and Power Monitor with an I²C interface. The INA219AIDCNR monitors both shunt drop and supply voltage, with programmable conversion times and filtering. A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes. An additional multiplying register calculates power in watts. The I²C interface features 16 programmable addresses. The INA219 is available in two grades: A and B. The B grade version has higher accuracy and higher precision specifications. The INA219AIDCNR senses across shunts on buses that can vary from 0 to 26V. The device uses a single +3 to +5.5V supply, drawing a maximum of 1mA of supply current.
