INA139QPWRQ1 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 input voltage of the differential shunt input, with absolute maximum common-mode of -0.3 V to 60 V for INA139-Q1 and differential (VIN+) - (VIN-) limited to -40 V to 2 V. |
| 2 | VIN+ | power_in | Positive input voltage of the differential shunt input, with recommended common-mode voltage of 2.7 V to 40 V for INA139-Q1 and absolute maximum of -0.3 V to 60 V. |
| 3 | NC | unconnected | Not connected internally. |
| 4 | GND | power_in | Ground reference for the device. |
| 5 | NC | unconnected | Not connected internally. |
| 6 | OUT | output | Output current; the analog output absolute maximum is -0.3 V to 40 V. |
| 7 | NC | unconnected | Not connected internally. |
| 8 | V+ | power_in | Power supply voltage; recommended range is 2.7 V to 40 V for INA139-Q1 with absolute maximum of -0.3 V to 60 V. |
