Description：

The INA139-Q1 and INA169-Q1 (INA1x9-Q1) arehigh-side, unidirectional, current shunt monitors. Wideinput common-mode voltage range, high-speed, lowquiescent current, and TSSOP-8 packaging enableuse in a variety of applications.The device converts a differential input voltage to acurrent output. This current is converted back to avoltage with an external load resistor that sets anygain from 1 to over 100. Although designed forcurrent shunt measurement, the circuit invitescreative applications in measurement and levelshifting.Both the INA139-Q1 and INA169-Q1 are available ina TSSOP-8 package, and are specified for the –40°Cto +125°C temperature range.
