INA270AQDRQ1 from Texas Instruments, in a SOIC-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 | IN- | input | Negative input; connect to the load side of the shunt resistor. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | PRE OUT | output | Pre-amplifier output with a 96-kΩ output impedance; connect to the input of an external filter whose output drives BUF IN. |
| 4 | BUF IN | input | Input to the output buffer stage; connect to the output of the filter fed from PRE OUT. |
| 5 | OUT | output | Current-sense amplifier voltage output. |
| 6 | VS | power_in | Power supply input, 2.7 V to 18 V (absolute maximum 18 V). |
| 7 | NC | unconnected | Not internally connected; the datasheet says to connect this pin to ground. |
| 8 | IN+ | input | Positive input; connect to the supply side of the shunt resistor. Common-mode range is -16 V to +80 V. |
