INA163UA from Texas Instruments, in a SOIC-14. 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 | VO1 | output | Output terminal 1 from internal instrumentation amplifier circuit |
| 2 | NC | unconnected | No internal connection |
| 3 | GS1 | passive | Gain-setting resistor terminal; external resistor RG connects between pins 3 and 12 to set gain as G = 1 + 6000/RG |
| 4 | VIN− | power_in | Negative differential input signal terminal; input signal voltage range (V−)−0.5V to (V+)+0.5V with maximum current of 10mA |
| 5 | VIN+ | power_in | Positive differential input signal terminal; input signal voltage range (V−)−0.5V to (V+)+0.5V with maximum current of 10mA |
| 6 | V− | power_in | Negative power supply rail; operating voltage range ±4.5V to ±18V |
| 7 | NC | unconnected | No internal connection |
| 8 | Sense | output | Output sense terminal for feedback loop compensation; low-impedance connection to load maintains common-mode rejection ratio greater than 100dB |
| 9 | VO | output | Primary output signal terminal with voltage swing (V+)−2 to (V+)−1.8 volts and (V−)+2 to (V−)+1.8 volts into 2kΩ load; maximum short-circuit current ±60mA continuous to ground |
| 10 | Ref | input | Reference voltage input terminal; externally applied voltage is summed with the output signal for offset voltage adjustment |
| 11 | V+ | power_in | Positive power supply rail; operating voltage range ±4.5V to ±18V |
| 12 | GS2 | passive | Gain-setting resistor terminal; external resistor RG connects between pins 3 and 12 to set gain as G = 1 + 6000/RG |
| 13 | NC | unconnected | No internal connection |
| 14 | VO2 | output | Output terminal 2 from internal instrumentation amplifier circuit |
