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. |
