Exact-Part Selection Insight
The stated 50Wx2@4Ω output-power condition is tied to the amplifier’s 4.5V~26V supply range and the load condition embedded in that rating. Thermal design, speaker impedance and available supply voltage must be evaluated together before using the headline wattage as a continuous design target.
Selection Notes
- Package: HTSSOP-32-6.1mm
- Supply voltage: 4.5V~26V
- Output Power: 50Wx2@4Ω
- Speaker Channels: 2-Channel
- Operating Temperature: -40℃~+85℃
Application Fit
This exact part is appropriate for designs that require a audio amplifier with the confirmed package and electrical/function parameters above. Final fit depends on the surrounding circuit, interface, thermal and mechanical requirements of the target design.
Design Considerations
Confirm the available supply rail stays inside the stated operating range, including startup and transient conditions.
Check current, power dissipation and board thermal conditions at the intended operating point rather than using the headline rating alone.
Use the exact HTSSOP-32-6.1mm footprint/package definition when checking PCB land pattern, assembly clearance and sourcing equivalence.

Request a Quote
To request a quotation, provide the manufacturer part number, required quantity, destination, target Date Code if applicable, and any testing or inspection requirements.
If a lower-power stereo Class-D amplifier fits the speaker and supply budget, review TPA3110D2PWPR (15 W per channel at 16 V into 8 ohms under TI’s specified distortion conditions) beside this 50-W-class TPA3116D2 (50 W per channel at 21 V into 4 ohms). The 28-pin PWP and 32-pin DAD layouts, available output power and supply requirements differ; redesign and speaker-load checks are necessary.
