INA282AIDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | -IN | input | Negative input connected to shunt resistor for measuring voltage on the negative side; common-mode range from -14V to +80V independent of V+ supply. |
| 2 | GND | power_in | Ground reference. |
| 3 | REF2 | input | Reference voltage connection for output bias adjustment; reference input voltage range from 0 to VGND+9V with typical value 2.048V. |
| 4 | NC | unconnected | No internal connection; pin should be left floating or connected to GND. |
| 5 | OUT | output | Output voltage proportional to sensed current; swing range from GND+0.015V to (V+)-0.17V with RL=10kΩ; maximum 1nF capacitive load. |
| 6 | V+ | power_in | Positive power supply; operating range +2.7V to +18V; supports maximum 900μA quiescent current. |
| 7 | REF1 | input | Reference voltage connection for output bias adjustment; reference input voltage range from 0 to VGND+9V with typical value 2.048V. |
| 8 | +IN | input | Positive input connected to shunt resistor for measuring voltage on the positive side; common-mode range from -14V to +80V independent of V+ supply. |
