INA126U 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 | RG | passive | Gain setting pin; for gains greater than 5, place a gain resistor between pins 1 and 8. |
| 2 | V-IN | power_in | Negative input of the instrumentation amplifier. |
| 3 | V+IN | power_in | Positive input of the instrumentation amplifier. |
| 4 | V- | power_in | Negative power supply; operating range ±1.35V to ±18V. |
| 5 | Ref | input | Reference input; this pin must be driven by low impedance source or grounded. |
| 6 | VO | output | Output of the instrumentation amplifier. |
| 7 | V+ | power_in | Positive power supply; operating range ±1.35V to ±18V. |
| 8 | RG | passive | Gain setting pin; for gains greater than 5, place a gain resistor between pins 1 and 8. |
