INA141UA 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 | J | input | Gain select pin (shorted to pin 8): G = 10V/V if not shorted, G = 100V/V if shorted; a 0.5Ω series resistance reduces gain by 0.1%. |
| 2 | V-IN | power_in | Negative (inverting) input, protected to ±40V. |
| 3 | V+IN | power_in | Positive (noninverting) input, protected to ±40V. |
| 4 | V- | power_in | Negative supply. |
| 5 | Ref | input | Reference input; this pin must be driven from a low impedance to maintain good CMR. |
| 6 | VO | output | Amplifier output. |
| 7 | V+ | power_in | Positive supply. |
| 8 | J | input | Gain select pin (shorted to pin 1): G = 10V/V if not shorted, G = 100V/V if shorted; a 0.5Ω series resistance reduces gain by 0.1%. |
