INA296B4QDDFRQ1 from Texas Instruments, in a TSOT-23-8. 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 | Current-sense amplifier negative input; for high-side use connect to the load side of the sense resistor, and for low-side use connect to the ground side of the sense resistor. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | REF2 | input | Reference 2 voltage input; connect to a potential from 0 V to VS, and it has no operational difference from REF1. |
| 4 | NC | unconnected | Reserved pin that must be connected to ground. |
| 5 | OUT | output | Amplifier output voltage; the output can range from as low as 20 mV to as high as 200 mV below the supply voltage. |
| 6 | VS | power_in | Power supply input, 2.7 V to 20 V. |
| 7 | REF1 | input | Reference 1 voltage input; connect to a potential from 0 V to VS, and it has no operational difference from REF2. |
| 8 | IN+ | input | Current-sense amplifier positive input; for high-side use connect to the bus-voltage side of the sense resistor, and for low-side use connect to the load side of the sense resistor. |
