INA138QPWRQ1

Texas Instruments · Current Sense Amplifiers · TSSOP-8

INA138QPWRQ1 from Texas Instruments, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN- power_in Negative analog input of the differential sense voltage; for INA138-Q1 the common-mode range is 2.7 V to 36 V recommended and absolute maximum is -0.3 V to 60 V.
2 VIN+ power_in Positive analog input of the differential sense voltage; for INA138-Q1 the common-mode range is 2.7 V to 36 V recommended and absolute maximum is -0.3 V to 60 V, independent of the supply voltage.
3 NC unconnected No internal connection; leave unconnected.
4 GND power_in Ground reference for the device.
5 NC unconnected No internal connection; leave unconnected.
6 OUT output Output current pin that sources a current proportional to the differential input, converted to voltage by an external load resistor; IOUT must be kept below 400 µA per the datasheet equation, and analog output absolute maximum is -0.3 V to 40 V.
7 NC unconnected No internal connection; leave unconnected.
8 V+ power_in Power-supply pin; for INA138-Q1 the recommended supply range is 2.7 V to 36 V (5 V nominal) and absolute maximum is -0.3 V to 60 V.
