INA126EA from Texas Instruments, in a VSSOP-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 RG passive Gain-set pin. Connect an external gain resistor RG between pin 1 and pin 8 for gains greater than 5 V/V. Gain = 5 + 80 kΩ / RG.
2 V-IN input Inverting (negative) analog input of the instrumentation amplifier.
3 V+IN input Non-inverting (positive) analog input of the instrumentation amplifier.
4 V- power_in Negative supply rail. Operates at −1.35 V to −18 V for split-supply operation, or ground for single-supply operation (2.7 V to 36 V total).
5 Ref input Reference input. Sets the zero-output voltage; must be driven from a low-impedance source or tied to ground. Any impedance at this pin degrades common-mode rejection.
6 VO output Amplifier output. VO = (V+IN − V-IN) × G + VRef, where G = 5 + 80 kΩ / RG.
7 V+ power_in Positive supply rail. Operates at +1.35 V to +18 V (split) or 2.7 V to 36 V (single supply, referenced to V-).
8 RG passive Gain-set pin. Connect an external gain resistor RG between pin 1 and pin 8 for gains greater than 5 V/V. Gain = 5 + 80 kΩ / RG.

Provenance

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

  • Datasheet: Texas Instruments datasheet (38 pp, sha256 4977bc0100b1ff1c, 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.
