INA139-Q1 Datasheet PDF - TI

●The INA139-Q1 and INA169-Q1 (INA1x9-Q1) are high-side, unidirectional, current shunt monitors. Wide input common-mode voltage range, high-speed, low quiescent current, and 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-Q1 and INA169-Q1 are available in a TSSOP-8 package, and are specified for the –40°C to +125°C temperature range.
