INA101KU from Texas Instruments, in a SOIC-16-300mil. 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 | Output | output | Output of the instrumentation amplifier, rated ±10V minimum at ±5mA minimum and referenced to the Common pin. |
| 2 | +VCC | power_in | Positive power supply, rated ±15V with a ±5V to ±20V supply range. |
| 3 | -Input | input | Inverting input of the instrumentation amplifier, with 10^10 Ω input impedance. |
| 4 | Gain Sense 1 | passive | Gain sense connection that reduces gain error from wiring or socket resistance when connected at the RG resistor. |
| 5 | Gain Set 1 | passive | RG gain-setting resistor connection, with gain G = 1 + (40kΩ/RG). |
| 6 | Offset Adj. | passive | Offset adjust pin for an optional potentiometer that trims input offset voltage. |
| 7 | Offset Adj. | passive | Offset adjust pin for an optional potentiometer that trims input offset voltage. |
| 8 | NC | unconnected | No internal connection. |
| 9 | NC | unconnected | No internal connection. |
| 10 | A1 Output | passive | Output of input amplifier A1, brought out on the package. |
| 11 | A2 Output | passive | Output of input amplifier A2, brought out on the package. |
| 12 | Gain Set 2 | passive | RG gain-setting resistor connection, with gain G = 1 + (40kΩ/RG). |
| 13 | Gain Sense 2 | passive | Gain sense connection that reduces gain error from wiring or socket resistance when connected at the RG resistor. |
| 14 | +Input | input | Non-inverting input of the instrumentation amplifier, with 10^10 Ω input impedance. |
| 15 | -VCC | power_in | Negative power supply, rated ±15V with a ±5V to ±20V supply range. |
| 16 | Common | passive | Output reference terminal, normally grounded; series resistance above 0.1Ω degrades CMR below 106dB. |
