Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll inspect the part metadata, symbol, footprint, and pins; locate the official datasheet if needed; update the Datasheet property; then cross-check everything and report mismatches.

  • Function: high-fidelity, ultra-low-EMI, anti-clipping mono Class-D audio power amplifier.
  • Filterless differential/BTL output.

Review complete. Pin numbering/names and SOP-8 footprint mapping are correct; flagged issues include an inaccurate “OpAmps” description, blank Part Type, unspecified pin types, missing pin descriptions, and a non-official LCSC Datasheet URL. Since the Datasheet property was already populated, it was not changed.

Key Datasheet Specifications
  • Function: high-fidelity, ultra-low-EMI, anti-clipping mono Class-D audio power amplifier.
  • Filterless differential/BTL output.
  • Output power: 3.5 W at VDD = 5.0 V, RL = 4 ohm, THD+N = 10%.
  • The current official product page also states 5.5 W at VDD = 5.0 V, RL = 2 ohm, THD+N = 10%; the older V1.21 PDF front page states 3.0 W at VDD = 3.7 V, RL = 2 ohm.
  • THD+N: 0.05% at 1 W into 4 ohm, 1 kHz.
  • Shutdown current: 0.01 uA.
  • Features: anti-clipping control, click/pop suppression, over-current protection, thermal protection, undervoltage malfunction prevention, EDMA low-loss output stage, and AROC EMI suppression.
  • Supported packages: SOP8L, SOP8L-PP, and DFN8L 5 mm x 6 mm.
  • Typical application components shown: 1 uF supply bypass capacitor, 1 uF BYPASS capacitor, two 1 uF input coupling capacitors, and two 12 kohm input resistors.

The terminal numbering and names exactly match the datasheet top-view pinout.
Footprint Cross-Check
  • Eight rectangular SMD pads are present.
  • Pad pitch along each side is 1.27 mm.
  • Opposing pad-center span is approximately 5.424 mm.
  • Pad size is approximately 0.70 mm x 1.525 mm.
  • The layout is consistent with a common SOP-8 150 mil footprint and the pad-to-pin mapping matches the datasheet top view.
  • The official three-page V1.21 datasheet does not provide an SOP8L mechanical dimension table or recommended land pattern. Therefore, the exact land-pattern dimensions cannot be conclusively validated against the official datasheet alone.
Mismatches and Quality Flags
  1. Description mismatch: “Audio Power OpAmps” misclassifies the HT6873. Recommended description: “3.5 W ultra-low-EMI anti-clipping mono Class-D audio power amplifier, SOP-8 150 mil.”
  2. Missing Part Type: the Part Type property is blank; it should identify an audio power amplifier / integrated circuit.
  3. Missing pin descriptions: all eight terminals lack the datasheet-derived Pin Description property.
  4. Missing pin electrical types: all terminal Pin Type properties are Unspecified. CTRL, BYPASS, IN-, and IN+ should be analog/input-class pins; OUT+ and OUT- outputs; VDD power; GND ground.
  5. Datasheet link quality: a Datasheet URL is present, but it points to an LCSC product page rather than the official direct PDF. No update was made because the user requested an update only when the property was absent.
  6. Footprint verification limitation: the pad pattern appears correct for SOP-8 150 mil, but the official datasheet lacks dimensional package/land-pattern data, so a manufacturer-drawing-level verification is not possible from the available official document.
Overall Assessment
The symbol pin names, numbering, and footprint pin mapping are correct. The main issues are metadata quality and missing terminal semantics, not a detected electrical pinout error. The footprint is conventionally appropriate for SOP-8 150 mil, with the noted limitation that exact dimensions cannot be checked against this datasheet revision.
