TLC2274AIDR

Texas Instruments · Precision OpAmps · SOIC-14

TLC2274AIDR from Texas Instruments, in a SOIC-14. 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 op-amp channel 1. Rail-to-rail output stage; can source/sink up to ±50 mA (absolute max). Short-circuit protected to either supply rail.
2 1IN- input Inverting input of op-amp channel 1. High-impedance CMOS input, typical bias current 1 pA. Input voltage range V(DD-) to V(DD+) - 1.5 V (common-mode).
3 1IN+ input Non-inverting input of op-amp channel 1. High-impedance CMOS input, typical bias current 1 pA. Common-mode range includes the negative rail.
4 VDD+ power_in Positive (highest) supply rail. Operating range ±2.2 V to ±8 V split, or up to 16 V single-supply relative to VDD-. Absolute max 8 V vs midpoint.
5 2IN+ input Non-inverting input of op-amp channel 2. High-impedance CMOS input, typical bias current 1 pA.
6 2IN- input Inverting input of op-amp channel 2. High-impedance CMOS input, typical bias current 1 pA.
7 2OUT output Output of op-amp channel 2. Rail-to-rail output stage; can drive up to ±50 mA (absolute max). Short-circuit protected.
8 3OUT output Output of op-amp channel 3. Rail-to-rail output stage; can drive up to ±50 mA (absolute max). Short-circuit protected.
9 3IN- input Inverting input of op-amp channel 3. High-impedance CMOS input, typical bias current 1 pA.
10 3IN+ input Non-inverting input of op-amp channel 3. High-impedance CMOS input, typical bias current 1 pA.
11 VDD- power_in Negative (lowest) supply rail. Tie to GND for single-supply operation, or to a negative rail for split-supply. Absolute max -8 V vs midpoint.
12 4IN+ input Non-inverting input of op-amp channel 4. High-impedance CMOS input, typical bias current 1 pA.
13 4IN- input Inverting input of op-amp channel 4. High-impedance CMOS input, typical bias current 1 pA.
14 4OUT output Output of op-amp channel 4. Rail-to-rail output stage; can drive up to ±50 mA (absolute max). Short-circuit protected.

CAD (KiCad official)

  • Symbol: TLC2274AIDR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: tlc2274aidr-etched.step / tlc2274aidr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc2274aidr.step / tlc2274aidr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tlc2274aidr.step 195 KB You want the bare part, or you mark your own boards.
tlc2274aidr-etched.step 2.1 MB You want the part with TLC2274AIDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 556 faces against 237 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.
