Description

The INA139 and INA169 are high-side, unipolar, current shunt monitors. Wide input common-mode voltage range, high-speed, low quiescent current, and tiny SOT23 packag- ing enable use in a variety of applications.

Input common-mode and power-supply voltages are inde- pendent and can range from 2.7V to 40V for the INA139 and 2.7V to 60V for the INA169. Quiescent current is only 60?A, whic permits connecting the power supply to either side of the current measurement shunt with minimal error.

The INA169 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 cir- cuit invites creative applications in measurement and level shifting.

Both the INA139 and INA169 are available in SOT23-5 packages and are specified for the -40 to +85 industrial temperature range.
