INA139/3K Current Monitor IC

the IC INA139 is one of the regulator ics for current measurement. the ina169 and ina139 ics, which belong to the same family, are used in various applications as unipolar, high-speed devices packaged in small sot-23. the common inputs and supply voltages operate independently within the voltage range of 2.7 to 40 volts. the quiescent current of this ic is only 60 microamperes, allowing the power supply to connect to the current measurement section and obtain its value with minimal error at the output. in fact, the function of the ina139 ic is to convert input voltage values into output current.
