INA129U

Texas Instruments · Instrumentation OpAmps · SOIC-8

INA129U 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 RG passive Gain setting pin; connect external resistor between pins 1 and 8 for gain greater than 1.
2 VIN- power_in Negative input; ±40V overvoltage protected.
3 VIN+ power_in Positive input; ±40V overvoltage protected.
4 V- power_in Negative power supply; ±2.25V to ±18V dual supply range.
5 REF input Reference input; must be driven by low impedance source or grounded.
6 VO output Output; VO = G × (VIN+ - VIN-) + VREF.
7 V+ power_in Positive power supply; ±2.25V to ±18V dual supply range.
8 RG passive Gain setting pin; connect external resistor between pins 1 and 8 for gain greater than 1.
