OPA2348AIDCNR

Texas Instruments · Operational Amplifier · SOT-23-8

OPA2348AIDCNR from Texas Instruments, in a SOT-23-8. 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 OUTA output Channel A op-amp output. Rail-to-rail output stage; can swing to within ~25mV of either supply rail with a 100kΩ load. Short-circuit protected (typ ±10mA Isc).
2 -INA input Channel A inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Typical input bias current ±0.5pA.
3 +INA input Channel A non-inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Input signal current must be limited to 10mA if driven beyond the supply rails by more than 0.5V.
4 V- power_in Negative supply / ground rail. Total supply (V+ minus V-) must not exceed 7.5V absolute maximum; single-supply operation from 2.1V to 5.5V is typical, with V- tied to ground.
5 +INB input Channel B non-inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Input signal current must be limited to 10mA if driven beyond the supply rails by more than 0.5V.
6 -INB input Channel B inverting input. Rail-to-rail CMOS input; common-mode range (V-)-0.2V to (V+)+0.2V. Typical input bias current ±0.5pA.
7 OUTB output Channel B op-amp output. Rail-to-rail output stage; can swing to within ~25mV of either supply rail with a 100kΩ load. Short-circuit protected (typ ±10mA Isc).
8 V+ power_in Positive supply rail. Single-supply range 2.1V to 5.5V (specified 2.5V to 5.5V). Bypass to V- with a 0.1µF ceramic near the pin. Total quiescent current is typ 45µA/channel (90µA for dual).

CAD (KiCad official)

  • Symbol: OPA2348AIDCNR
  • Footprint: Package_TO_SOT_SMD:SOT-23-8
  • 3D model: SOT-23-8 (KiCad packages3D, STEP)
  • 3D model files: opa2348aidcnr-etched.step / opa2348aidcnr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa2348aidcnr.step / opa2348aidcnr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
opa2348aidcnr.step 123 KB You want the bare part, or you mark your own boards.
opa2348aidcnr-etched.step 2.6 MB You want the part with OPA2348AIDCNR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 633 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.
