INA133UA

Texas Instruments · Differential Amplifiers · SOIC-8

INA133UA 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 Ref input Reference input with maximum voltage VS and 25kΩ resistor connected to op-amp non-inverting terminal
2 -IN input Negative (inverting) input with maximum voltage 2×VS and 25kΩ resistor connected to op-amp inverting terminal
3 +IN input Positive (non-inverting) input with maximum voltage 2×VS and 25kΩ resistor connected to op-amp non-inverting terminal
4 V- power_in Negative (lowest) supply voltage, 0 to 36V total span with V+
5 Sense input Sense input with maximum voltage VS and 25kΩ resistor connected to op-amp inverting terminal
6 Output output Amplifier output, operating voltage range (V-)+ 1V to (V+)-1.5V for gain error less than 0.1%
7 V+ power_in Positive (highest) supply voltage, 0 to 36V total span with V-
8 NC unconnected Not connected internally, can be left floating

  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: ina133ua-etched.step / ina133ua-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina133ua.step / ina133ua.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (41 pp, sha256 15b53f9e067f70ea, retrieved 2026-10-01, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-4-5-20251001 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
