OPA2333AIDR

Texas Instruments · Precision OpAmps · SOP-8

OPA2333AIDR from Texas Instruments, in a SOP-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 OUT A output Amplifier A output. Rail-to-rail output that swings within 50 mV of the supply rails with a 10 kΩ load. Short-circuit current ±5 mA typical.
2 -IN A input Amplifier A inverting input. High-impedance CMOS input with common-mode range extending 100 mV beyond both rails ((V-) - 0.1 V to (V+) + 0.1 V). Diode-clamped to the supply rails; limit currents to ≤10 mA if signal swings > 0.3 V beyond the rails.
3 +IN A input Amplifier A non-inverting input. High-impedance CMOS input with rail-to-rail common-mode range. Diode-clamped to the supply rails.
4 V- power_in Negative power-supply pin. Ground for single-supply operation, or the negative rail for dual-supply operation. Supply range: total V+ to V- between 1.8 V and 5.5 V (±0.9 V to ±2.75 V dual-supply).
5 +IN B input Amplifier B non-inverting input. High-impedance CMOS input with rail-to-rail common-mode range. Diode-clamped to the supply rails.
6 -IN B input Amplifier B inverting input. High-impedance CMOS input with rail-to-rail common-mode range. Diode-clamped to the supply rails; limit currents to ≤10 mA if signal swings > 0.3 V beyond the rails.
7 OUT B output Amplifier B output. Rail-to-rail output that swings within 50 mV of the supply rails with a 10 kΩ load. Short-circuit current ±5 mA typical.
8 V+ power_in Positive power-supply pin. Supply range 1.8 V to 5.5 V total (V+ to V-). Quiescent current 17 µA per amplifier (34 µA total, typ).

Two STEP files. Same geometry, different body top:

File Size Use it when
opa2333aidr.step 122 KB You want the bare part, or you mark your own boards.
opa2333aidr-etched.step 2.4 MB You want the part with OPA2333AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 592 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: Texas Instruments datasheet (33 pp, sha256 6b0a431c3b5a3ea7, retrieved 2026-08-17, tier: manufacturer)
  • 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).
