INA132U

Texas Instruments · Differential Amplifiers · SOIC-8

INA132U from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Ref input Reference input. Drive with a low-impedance source; sets the output reference (zero) voltage. Swapping pins 1 and 3 will degrade CMR.
2 -In input Negative (inverting) input of the difference amplifier. Internally tied to the op amp inverting input through a 40kΩ resistor.
3 +In input Positive (non-inverting) input of the difference amplifier. Internally tied to the op amp non-inverting input through a 40kΩ resistor.
4 V- power_in Negative supply rail. Connect to ground for single-supply operation (2.7V to 36V) or to a negative rail for dual-supply operation (±1.35V to ±18V).
5 Sense input Sense input. Drive with a low-impedance source; typically tied to Output for standard difference-amp operation, or to a remote load node for Kelvin sensing. Swapping pins 2 and 5 will degrade CMR.
6 Output output Amplifier output. Unity-gain difference of (+In) - (-In) referenced to the Ref pin. Rail-to-rail swing within ~1V of V+ and 0.5V of V- with a 100kΩ load.
7 V+ power_in Positive supply rail. Accepts 2.7V to 36V single-supply or +1.35V to +18V dual-supply.
8 NC unconnected No internal connection. Leave floating (datasheet says 保持未连接 / keep unconnected).

Provenance

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

  • Datasheet: Texas Instruments datasheet (24 pp, sha256 4c07095c36dc4913, retrieved 2026-08-17, 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: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
