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 | Vo-(L) | output | Negative BTL output of the left channel. Class-D PWM output; connects directly to one terminal of the left speaker (no output filter required for inductive loads). |+| 2 | GND | power_in | Power ground. One of three ground pins (2, 9, 15) that carry the Class-D output-stage return current; keep the ground trace wide and short to the decoupling capacitors. |+| 3 | Vo+(L) | output | Positive BTL output of the left channel. Class-D PWM output; connects to the other terminal of the left speaker. |+| 4 | VDD | power_in | Power supply for the left and right output stages. Operating range 2.2V-5.5V (6.0V absolute max). Decouple with a 10µF bulk capacitor and a 0.1µF ceramic close to the pin; shared with pin 13. |+| 5 | SDB | input | Shutdown control (active-low). Drive low (≤0.4V) to place the device in shutdown (ISD ≈ 0.1µA); drive high (≥1.2V) for normal operation. Datasheet also labels this pin 'SHUTDOWN' in the pin-configuration drawing. |+| 6 | AGND | power_in | Analog ground for both left and right input/preamp stages. Must be tied to the main ground plane. |+| 7 | INL | input | Left-channel single-ended audio input. AC-couple through a series input capacitor and input resistor Ri (typ. 150kΩ, 0.22µF for fc ≈ 4.8Hz). Ri sets the pre-amplifier gain per Rf/Ri. |+| 8 | BYPASS | passive | Internal mid-supply reference bypass. Connect a ceramic bypass capacitor (typ. 2.2µF) to ground; this capacitor sets the start-up ramp time (≈215-265ms with 2.2µF). |+| 9 | GND | power_in | Power ground. One of three ground pins (2, 9, 15) that carry the Class-D output-stage return current. |+| 10 | INR | input | Right-channel single-ended audio input. AC-couple through a series input capacitor and input resistor Ri (typ. 150kΩ, 0.22µF). |+| 11 | AVDD | power_in | Analog power supply for the left and right pre-amp/analog sections. Typically tied to the same rail as VDD (2.2V-5.5V) with local 0.1µF decoupling to AGND. |+| 12 | Radio Enhance | input | Radio-enhance mode control (active-high). Drive high to enable the radio-enhance function for improved performance with weak radio signals; drive low for normal (higher-efficiency) mode. Recommended to keep low when the radio function is not needed. |+| 13 | VDD | power_in | Power supply for the left and right output stages (shared with pin 4). Operating range 2.2V-5.5V. Decouple locally with 0.1µF ceramic. |+| 14 | Vo+(R) | output | Positive BTL output of the right channel. Class-D PWM output; connects directly to one terminal of the right speaker. |+| 15 | GND | power_in | Power ground. One of three ground pins (2, 9, 15) that carry the Class-D output-stage return current. |+| 16 | Vo-(R) | output | Negative BTL output of the right channel. Class-D PWM output; connects to the other terminal of the right speaker. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Lyontek Inc |+| Package | SOP-16 |+| Category | Op-amp/Cmp |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `LY8212SLT`++## CAD (KiCad official)++- Symbol: `LY8212SLT`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Lyontek Inc datasheet](docs/ly8212slt-datasheet.pdf) (9 pp, sha256 `b1be743829a791e2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
