INA296A4IDR 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 current-sense amplifier input: connect to the load side of the sense resistor for high-side use, or to the ground side for low-side use; the common-mode range is -5 V to 110 V. |
| 2 | GND | power_in | Device ground reference; the REF1 and REF2 inputs are specified from 0 V to VS relative to this pin. |
| 3 | REF2 | input | Reference 2 input, specified from 0 V to VS; with 0 V differential input the output is set to the average of REF1 and REF2, so it is tied to a supply, ground, or low-impedance reference, or to the other REF pin through a divider. |
| 4 | NC | unconnected | Reserved pin; the datasheet states it must be connected to ground. |
| 5 | OUT | output | Output voltage of the amplifier, referenced to the REF pin voltage; absolute maximum range is GND - 0.3 V to VS + 0.3 V. |
| 6 | VS | power_in | Power supply input, specified at 2.7 V to 20 V (absolute maximum 22 V). |
| 7 | REF1 | input | Reference 1 input, specified from 0 V to VS; with 0 V differential input the output is set to the average of REF1 and REF2, so it is tied to a supply, ground, or low-impedance reference, or to the other REF pin through a divider. |
| 8 | IN+ | input | Positive current-sense amplifier input: connect to the bus-voltage side of the sense resistor for high-side use, or to the load side for low-side use; the common-mode range is -5 V to 110 V. |
