TLC27L2CDR

Texas Instruments · Operational Amplifier · SOIC-8

TLC27L2CDR 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 Amplifier 1 output. Rail-to-negative-rail output; short-circuit current unlimited at TA ≤ 25 °C (see abs-max). Max ±30 mA output current.
2 1IN- input Amplifier 1 inverting input. High-impedance CMOS input (~10^12 Ω), input bias current typ 0.6 pA at 25 °C.
3 1IN+ input Amplifier 1 non-inverting input. Common-mode range extends 0.2 V below GND up to VDD-1 V (typ). High-impedance CMOS input.
4 GND power_in Negative supply / ground reference. In single-supply mode connects to 0 V; total current out of GND max 45 mA.
5 2IN+ input Amplifier 2 non-inverting input. Same characteristics as 1IN+.
6 2IN- input Amplifier 2 inverting input. Same characteristics as 1IN-.
7 2OUT output Amplifier 2 output. Same characteristics as 1OUT.
8 VDD power_in Positive supply. 3 V to 16 V (C suffix) or 4 V to 16 V (I/M suffix); absolute maximum 18 V. Total current into VDD max 45 mA. Supply current typ 20 μA (two amplifiers, VDD=5 V).

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
tlc27l2cdr.step 122 KB You want the bare part, or you mark your own boards.
tlc27l2cdr-etched.step 1.8 MB You want the part with TLC27L2CDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 447 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 (48 pp, sha256 0e4a5e05f308347e, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
