TLC2272CDR

Texas Instruments · Precision OpAmps · SOIC-8

TLC2272CDR 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 1OUT output Output of amplifier 1. Rail-to-rail output stage, capable of swinging within millivolts of VDD+ and VDD-/GND. Output current limited to +/-50 mA absolute maximum.
2 1IN- input Inverting input of amplifier 1. High-impedance CMOS input with 1 pA typical bias current. Input voltage range includes the negative rail (VDD-/GND) up to VDD+ - 1.5 V.
3 1IN+ input Non-inverting input of amplifier 1. High-impedance CMOS input with 1 pA typical bias current. Common-mode range includes the negative rail.
4 VDD-/GND power_in Negative supply rail (split supply) or ground (single supply). For split-supply operation accepts -2.2 V to -8 V. For single-supply operation tie to GND; total supply must not exceed 16 V.
5 2IN+ input Non-inverting input of amplifier 2. High-impedance CMOS input with 1 pA typical bias current. Common-mode range includes the negative rail.
6 2IN- input Inverting input of amplifier 2. High-impedance CMOS input with 1 pA typical bias current.
7 2OUT output Output of amplifier 2. Rail-to-rail output stage. Output current limited to +/-50 mA absolute maximum.
8 VDD+ power_in Positive supply rail. Recommended range +2.2 V to +8 V (split supply) or 4.4 V to 16 V total between VDD+ and VDD-. Absolute maximum 8 V (split) with total current into VDD+ limited to +/-50 mA.

CAD (KiCad official)

  • Symbol: TLC2272CDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tlc2272cdr-etched.step / tlc2272cdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc2272cdr.step / tlc2272cdr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tlc2272cdr.step 122 KB You want the bare part, or you mark your own boards.
tlc2272cdr-etched.step 1.9 MB You want the part with TLC2272CDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 477 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
