HT8631BRTZ

HTCSEMI · Operational Amplifier · SOT-23-5

HT8631BRTZ from HTCSEMI, in a SOT-23-5. 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 INP input Non-inverting input of amplifier. Input voltage range is 0 V to VDD (rail-to-rail input).
2 GND power_in Ground pin. Connect to the most negative supply; all GND pads are connected on die.
3 INN input Inverting input of amplifier. Has the same 0 V to VDD input voltage range as INP.
4 OUT output Amplifier output. Rail-to-rail: swings to within ~10 mV of each supply rail into a light load. Short-circuit current ~80 mA.
5 VDD power_in Positive power supply. Operating range 2.5 V to 5.5 V (absolute max 6 V). Bypass locally with a ceramic capacitor to GND.

CAD (KiCad official)

  • Symbol: HT8631BRTZ
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ht8631brtz-etched.step / ht8631brtz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht8631brtz.step / ht8631brtz.glb are the bare package body.

Provenance

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

  • Datasheet: HTCSEMI datasheet (12 pp, sha256 a868afac1c6f624e, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
