HT8722ARZ

HTCSEMI · Operational Amplifier · SOP-8

HT8722ARZ from HTCSEMI, in a SOP-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 OUT A output Output of amplifier channel A. Rail-to-rail output; can source/sink about ±30 mA (Vs=3 V) or ±50 mA (Vs=5 V) with closed-loop output impedance ~10-12 Ω at 1 MHz (Av=1).
2 -IN A input Inverting input of amplifier channel A. Rail-to-rail CMOS input; input bias current 0.2 pA typ, offset current 0.1 pA typ at 25 °C.
3 +IN A input Non-inverting input of amplifier channel A. Rail-to-rail input range (0 V to Vs); differential input voltage rating ±6 V.
4 V- power_in Negative supply / ground pin. For single-supply operation tie to GND; total supply voltage V+ to V- must be between 2.7 V and 5.5 V (absolute max 6 V).
5 +IN B input Non-inverting input of amplifier channel B. Rail-to-rail input range (0 V to Vs).
6 -IN B input Inverting input of amplifier channel B. Rail-to-rail CMOS input with pA-level bias current.
7 OUT B output Output of amplifier channel B. Rail-to-rail output capable of driving ±30 mA (3 V) / ±50 mA (5 V) loads.
8 V+ power_in Positive supply pin. Single-supply operating range 2.7 V to 5.5 V (absolute maximum 6 V). Supply current is ~500 µA per amplifier at Vs=3 V, ~750 µA per amplifier at Vs=5 V.

CAD (KiCad official)

  • Symbol: HT8722ARZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: ht8722arz-etched.step / ht8722arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ht8722arz.step / ht8722arz.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ht8722arz.step 122 KB You want the bare part, or you mark your own boards.
ht8722arz-etched.step 1.8 MB You want the part with HT8722ARZ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 452 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: HTCSEMI datasheet (13 pp, sha256 f3e26f623cb62249, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
