INA169NA

Texas Instruments · Current Sense Amplifiers · SOT-23-5

INA169NA from Texas Instruments, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Output current pin. Sources a current proportional to (V_IN+ − V_IN−); an external load resistor R_L to GND converts this to an output voltage V_O = I_S × R_S × R_L / 1kΩ, setting a gain of 1 to >100.
2 GND power_in Device ground reference.
3 VIN+ input Positive input voltage. Connects to the more positive end of the external current-sense shunt resistor R_S on the high side of the load. Common-mode range 2.7 V to 60 V for the INA169.
4 VIN- input Negative input voltage. Connects to the load side of the external sense resistor R_S. Differential input (VIN+ − VIN−) sets the output current through internal 1 kΩ resistors.
5 V+ power_in Power supply voltage. 2.7 V to 60 V operating range for the INA169; independent of the input common-mode voltage. Quiescent current ~60 µA typical.
