Beschrijving

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. With some basic math, the output voltage gives you the current through the shunt resistor.

As current passes from V_IN+ through R_S to V_IN-, it creates a voltage drop across R_S. The op-amp inside of the INA169 chip measures the difference between the V_IN+ and V_IN- voltages and outputs a voltage based on that difference. The output of the op-amp is amplified through the internal transistor, which sources a current out of the INA169 chip. As that current passes through R_L to ground, a voltage level is generated at V_OUT.
