Not connected to PVCCR or AVCC. |+| 11 | LOUTN | output | Class-D 1/2-H-bridge negative output for left channel. |+| 12 | BSLN | passive | Bootstrap I/O for left channel, negative high-side FET (1uF bootstrap capacitor). |+| 13 | BSLP | passive | Bootstrap I/O for left channel, positive high-side FET (1uF bootstrap capacitor). |+| 14 | LOUTP | output | Class-D 1/2-H-bridge positive output for left channel. |+| 15 | PVCCL | power_in | Power supply for left channel H-bridge. Not connected to PVCCR or AVCC. |+| 16 | PGNDL | power_in | Power ground for left channel H-bridge. |+| 17 | NC | unconnected | Not connected. |+| 18 | PL | input | Reference voltage for power limit function. Input range 0 to 6.0V. |+| 19 | V2P5 | power_out | 2.5V reference for analog cells (bypass to ground with 1uF). |+| 20 | AGND | power_in | Analog ground. |+| 21 | VCLAMP | power_out | Internally generated voltage supply for bootstrap capacitors (bypass to ground with 1uF). |+| 22 | AVCC | power_in | High-voltage analog power supply, 8V to 26V. |+| 23 | SD | input | Shutdown signal for IC (low = shutdown, high = operational). TTL logic levels with compliance to VCC. Input range -0.3 to VCC. |+| 24 | NC | unconnected | Not connected. |+| 25 | PGNDR | power_in | Power ground for right channel H-bridge. |+| 26 | PVCCR | power_in | Power supply for right channel H-bridge. Not connected to PVCCL or AVCC. |+| 27 | ROUTP | output | Class-D 1/2-H-bridge positive output for right channel. |+| 28 | BSRP | passive | Bootstrap I/O for right channel, positive high-side FET (1uF bootstrap capacitor). |+| 29 | BSRN | passive | Bootstrap I/O for right channel, negative high-side FET (1uF bootstrap capacitor). |+| 30 | ROUTN | output | Class-D 1/2-H-bridge negative output for right channel. |+| 31 | PVCCR | power_in | Power supply for right channel H-bridge. Not connected to PVCCL or AVCC. |+| 32 | PGNDR | power_in | Power ground for right channel H-bridge. |+| 33 | EP | power_in | Exposed thermal pad. Connect to ground; must be soldered to a thermal land on the PCB for proper thermal and mechanical performance. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | QFN-32-EP(5x5) |+| Category | Op-amp/Cmp |+| Pins | 33 |++## Ordering variants++- `PAM8620TR`++## CAD (KiCad official)++- Symbol: `PAM8620TR`+- Footprint: `Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.3x3.3mm`+- 3D model: QFN-32-EP(5x5) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/pam8620tr-datasheet.pdf) (14 pp, sha256 `72a588634c47457e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
