Texas Instruments [India] Pvt. Ltd. Supplies Automotive Catalog High-Side Measurement Current Shunt Monitor. Texas Instruments [India] Pvt. Ltd. Offers assorted range of s amplifiers, linear amplifiers, semiconductors, clocks, timers, microcontrollers, data converters, etc. The Automotive Catalog High-Side Measurement Current Shunt Monitors of model numbersINA139 and INA169 are high-side, unipolar, current shunt monitors. Input common-mode and power-supply voltages are independent and can range from 2.7 V to 40 V for the INA139 and 2.7 V to 60 V for the INA169. Quiescent current is only 60 Μ A, which permits connecting the power supply to either side of the current measurement shunt with minimal error. The device converts a differential input voltage to a current output. This current is converted back to a voltage with an external load resistor that sets any gain from 1 to over 100. Although designed for current shunt measurement, the circuit invites creative applications in measurement and level shifting.
