Exact-Part Selection Insight
The stated 15Wx2@8Ω output-power condition is tied to the amplifier’s 8V~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-28-EP
- Supply voltage: 8V~26V
- Output Power: 15Wx2@8Ω
- 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-28-EP footprint/package definition when checking PCB land pattern, assembly clearance and sourcing equivalence.

For a higher-output-power TI stereo Class-D audio amplifier, compare TPA3116D2DADR (up to 50 W per channel at 21 V into 4 ohms, per TI conditions) with this TPA3110D2 design (15 W per channel at 16 V into 8 ohms, at 10% THD+N). The 32-pin DAD and 28-pin PWP packages and external thermal, supply and speaker-load constraints differ; these are not board-level drop-in options.
