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 | NC | unconnected | No connection. This pin is not internally bonded on the SSOP-10 package and should be left floating or tied to a convenient net per PCB layout preference. |+| 2 | VCC | power_in | Positive supply voltage input. Typical operating VCC=6V (3V to 9V typical range); absolute maximum 14V. Bypass to GND with a 100µF capacitor near the pin. Typical DC voltage 6.0V at test conditions. |+| 3 | NC | unconnected | No connection. This pin is not internally bonded on the SSOP-10 package and should be left floating. |+| 4 | VIN | input | Audio signal input to the PNP differential pair (via a PNP emitter follower Q1 that allows DC referencing of the source to GND). Input resistance ~27kΩ. DC-coupling is possible; add a series coupling capacitor if brush noise from the volume pot is an issue. Typical DC voltage 0V at no signal. |+| 5 | RIPPLE | passive | Ripple rejection filter terminal. Adding a bypass capacitor (Crip) from this pin to GND improves supply ripple rejection from -25dB to -45dB (fR=100Hz, VR=0.3Vrms). Typical DC voltage 2.40V at no signal. |+| 6 | NF | passive | Negative Feedback terminal. Voltage gain is fixed at Gv=40dB by internal resistors R4 and R5; the gain can be reduced by adding an external Rf per Gv=20log(R5+R4+Rf)/(R4+Rf). Recommend keeping gain ≥28dB. Typical DC voltage 0.62V at no signal. |+| 7 | PHASE | passive | Phase-compensation / oscillation-prevention terminal from the internal amplifier stage. Requires a small-temperature-coefficient capacitor with good frequency characteristics for stable operation. Typical DC voltage 0.64V at no signal. |+| 8 | PRE-GND | power_in | Pre-amplifier (signal) ground return. Kept separate from power ground to minimize output stage current coupling into the low-level pre-amp stage. Typical DC voltage 0V. |+| 9 | PW-GND | power_in | Power (output stage) ground return for the class-AB output transistors. Route with low-impedance traces to the supply return; keep separate from PRE-GND for best noise performance. Typical DC voltage 0V. |+| 10 | POUT | output | Audio power output. Drives loudspeaker load (typ. 4Ω or 8Ω) through a DC-blocking capacitor (e.g., 470µF). Delivers ~500-720mW into 4Ω at VCC=6V, THD=10%, and up to ~1100mW into 8Ω at VCC=9V. Typical DC voltage 2.61V (approx. VCC/2) at no signal. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UTC Unisonic Tech |+| Package | SSOP-10-150mil |+| Category | Op-amp/Cmp |+| Pins | 10 |++## Ordering variants++- `TA7368PG-R10-RR10-T`+- `TA7368PG-R10-R`+- `TA7368PG-R10-RD08-T`+- `TA7368PG-R10-RS08-T`+- `TA7368PG-R10-RS08-R`+- `TA7368PG-R10-RG09-T`++## CAD (KiCad official)++- Symbol: `TA7368PG-R10-R`+- Footprint: `Package_SO:SSOP-10_3.9x4.9mm_P1.00mm`+- 3D model: SSOP-10-150mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [UTC Unisonic Tech datasheet](docs/ta7368pg-r10-r-datasheet.pdf) (None pp, sha256 `c02ac91118e9bafa`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
