Key Features
- 4-channel Class D topology delivering up to 4 × 30 W into 4-ohm loads with over 90% efficiency at 24 V
- 112 dB SNR and 18 dB fixed gain enabling high-fidelity stereo or 2.1/4.0 speaker configurations without external op-amp stages
- Integrated diagnostic reporting and short-circuit protection on all 4 channels for reliable operation in consumer and automotive speakers
Applications
TPA3245DDV is designed for soundbars, smart speakers, and AV receivers requiring 4 independent high-power channels in a compact package. Its high efficiency at 24 V to 36 V supply rails reduces heatsink size in fanless desktop audio equipment. The 44-pin HTSSOP footprint simplifies multi-channel board layout for 2.1, 4.0, and bridged stereo amplifier configurations.

Frequently Asked Questions
How much output power does TPA3245DDV deliver per channel and at what supply voltage?
TPA3245DDV delivers up to 30 W per channel into a 4-ohm load when supplied at 24 V, and up to 45 W per channel in bridged mode at 36 V. With 4 independent channels and over 90% Class D efficiency, it achieves total output power above 100 W without requiring an external heatsink in typical soundbar designs.
How does TPA3245DDV's 112 dB SNR benefit a high-fidelity stereo amplifier design?
A 112 dB signal-to-noise ratio means the amplifier's noise floor is 112 dB below full-scale output, equivalent to less than 25 µW of residual noise at 30 W output. This performance meets audiophile-grade specifications and eliminates the need for external noise filtering stages in 2-channel or 2.1 speaker systems driven from digital audio sources.
What protection features does TPA3245DDV include to safeguard speakers in a consumer product?
TPA3245DDV integrates per-channel short-circuit protection, over-temperature shutdown triggered above 150°C junction temperature, and undervoltage lockout that disables outputs below a minimum supply threshold. These 3 protection mechanisms prevent speaker coil damage and IC destruction during fault conditions without requiring external protection relays on the 4 output channels.
For a compact soundbar using TPA3245DDV, what PCB area does the 44-pin HTSSOP package require?
The 44-pin HTSSOP package has a 7.7 mm × 14 mm body with 0.8 mm pin pitch, occupying approximately 108 mm² of PCB area for the IC plus a thermal pad. Combined with a few bulk capacitors and ferrite beads on each output, a complete 4-channel amplifier stage typically fits within 30 cm² on a 2-layer board inside a slim soundbar enclosure.
