The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output.

Input common-mode and power supply voltages are independent and can range from 2.7V to 60V on the INA169 and quiescent (sleep) current is only 60uA.

該INA169是一個“高邊電流監測器”，這意味著你將一個電阻（一個“分流電阻”），在正電源軌和INA169措施，在此電阻上的電壓降。的INA169輸出基於所測量的電壓降小電流。如果從INA169的輸出放置一個電阻接地，可以測量在輸出端的電壓。

輸入共模和電源電壓是獨立的，範圍從2.7V至60V的INA169和靜態（睡眠）電流僅為60uA的。
