HT4040BRTZ

HTCSEMI · Operational Amplifier · SOT-23-5

HT4040BRTZ 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 analog input of the amplifier. Input common-mode voltage range is 0 V to VDD (beyond-the-rails capable).
2 GND power_in Ground / negative supply. Connect to the most negative supply rail; all GND pads are connected on die.
3 INN input Inverting analog input of the amplifier. Same input voltage range as INP (0 V to VDD, beyond-the-rails capable).
4 OUT output Amplifier output. Rail-to-rail output, swings to within ~10mV of each supply rail; short-circuit current ~80mA.
5 VDD power_in Positive power supply pin. Operating range 2.5 V to 5.5 V (absolute maximum 6 V). Bypass with a local decoupling capacitor to GND.

CAD (KiCad official)

  • Symbol: HT4040BRTZ
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ht4040brtz-etched.step / ht4040brtz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht4040brtz.step / ht4040brtz.glb are the bare package body.

Provenance

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

  • Datasheet: HTCSEMI datasheet (6 pp, sha256 7a5e082d10e70867, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
