TLC1549IDR

Texas Instruments · Analog To Digital Converters (ADC) · SOIC-8

TLC1549IDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 REF+ input The upper reference voltage value (nominally VCC) is applied to REF+.
2 ANALOG IN input Analog signal input with driving source impedance ≤ 1 kΩ and driving source current capability ≥ 10 mA.
3 REF- input The lower reference voltage value (nominally ground) is applied to REF-.
4 GND power_in The ground return for internal circuitry.
5 CS input Chip select; a high-to-low transition resets the internal counters and enables DATA OUT and I/O CLOCK.
6 DATA OUT tri_state 3-state serial output for the A/D conversion result; high-impedance state when CS is high and active when CS is low.
7 I/O CLOCK input Serial I/O clock input; on the third falling edge analog input sampling begins and continues until the tenth falling edge.
8 VCC power_in Positive supply voltage.

CAD (KiCad official)

  • Symbol: TLC1549IDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tlc1549idr-etched.step / tlc1549idr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc1549idr.step / tlc1549idr.glb are the bare package body.

Provenance

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

  • Datasheet: Texas Instruments datasheet (20 pp, sha256 134c25af77335e0b, retrieved 2026-10-05, tier: manufacturer)
