Key Features
- Dual-channel Class D topology delivering 2x80 W (up to 110 W peak) output at high efficiency, minimizing heatsink requirements vs. Class AB designs
- 30 dB fixed gain with 22 kHz audio bandwidth and low harmonic distortion for clean reproduction across the full audible frequency range
- Compact 23-pin HSOP (R-PZFM-T23) surface-mount package simplifying PCB layout for space-constrained audio amplifier designs
Applications
The TDA8920BJ targets consumer audio applications including home theater receivers, soundbars, and active loudspeaker systems requiring 2x80 W stereo Class D amplification with minimal thermal management overhead. Its high switching efficiency reduces power dissipation compared to linear Class AB amplifiers, enabling fanless enclosure designs in flat-panel TVs and multimedia docking stations. Professional audio equipment manufacturers also use the TDA8920BJ in compact powered mixer channels and stage monitor amplifiers where board space and power budget are constrained.

Frequently Asked Questions
What output power and channel count does the TDA8920BJ deliver in a stereo audio design?
The TDA8920BJ is a 2-channel Class D amplifier rated at 2x80 W continuous output power with a 110 W peak capability. It operates with 30 dB gain across a 22 kHz audio bandwidth, making it suitable for stereo home theater, soundbar, and active speaker designs where high power density and efficiency matter.
How does the Class D topology of the TDA8920BJ reduce thermal dissipation compared to Class AB amplifiers?
Class D amplifiers like the TDA8920BJ use a high-frequency switching output stage that is either fully on or fully off, achieving efficiency well above 80% at rated power. This dramatically reduces power lost as heat compared to Class AB designs at 2x80 W output levels, allowing designers to reduce or eliminate heatsinking and lower system BOM cost in consumer audio enclosures.
Which package does the TDA8920BJ use and what does it mean for PCB layout?
The TDA8920BJ is housed in a 23-pin HSOP (JESD-30 code R-PZFM-T23) surface-mount package with an exposed thermal pad. The SMD footprint simplifies automated PCB assembly, and the thermal pad enables direct heat transfer to a copper pour or heatsink slug, supporting the 110 W peak power dissipation requirement within a compact board area.
