INA139-Q1 汽车类高侧测量电流并联监视器
The INA139 and INA169 are high-side, unipolar, current shunt monitors. Wide input common-mode voltage range, high-speed, low quiescent current, and tiny TSSOP-8 packaging enable use in a variety of applications.
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.
Both the INA139 and INA169 are available in TSSOP-8 and are specified for the –40°C to 125°C temperature range
