What are the key features of TAS5822MDCPR?
- 35 W per channel stereo Class-D output without external inductors, reducing BOM and board area
- Closed-loop architecture delivers 110 dB dynamic range for high-fidelity audio reproduction
- 96 kHz sample rate support with enhanced signal processing for audiophile-grade sound quality
- I2C control and I2S digital audio input simplify integration with application processors and DSPs
- Integrated analog-to-digital feedback loop eliminates output filter inductors in BTL configurations
What is TAS5822MDCPR used for?
TAS5822MDCPR is designed for smart speakers, soundbars, and portable wireless audio systems where high output power and small PCB footprint are both required. The 35 W per channel stereo output and inductor-less design allow engineers to build compact 2.0 or 2.1 channel systems without large output filter magnetics, simplifying thermal and mechanical design. It is also used in home theater amplifier modules and automotive rear-seat entertainment systems where 96 kHz digital audio fidelity and I2S interface compatibility with media processors are essential.

Frequently Asked Questions
How does the inductor-less design of TAS5822MDCPR reduce BOM complexity in a 35 W stereo smart speaker?
TAS5822MDCPR uses a closed-loop Class-D architecture that eliminates the external output filter inductors typically required in BTL configurations, removing 2 or more inductors that would otherwise be rated for 35 W at several amperes. This cuts BOM cost and saves at least 50 mm² of PCB area per channel, which is critical in compact smart speaker enclosures. The internal feedback loop also compensates for output impedance variations, maintaining low THD without relying on external LC filter characteristics.
Which audio sample rates does TAS5822MDCPR support, and how does the 96 kHz mode improve playback quality?
TAS5822MDCPR supports standard audio sample rates including 44.1 kHz, 48 kHz, and 96 kHz via its I2S digital input. Operating at 96 kHz doubles the temporal resolution compared to 48 kHz playback, extending the reproducible frequency response beyond 40 kHz and reducing aliasing artifacts in the audible band. Combined with the 110 dB dynamic range, 96 kHz mode allows TAS5822MDCPR to meet high-resolution audio standards such as Hi-Res Audio certification requirements for soundbars and premium wireless speakers.
What interface does TAS5822MDCPR use for configuration, and how complex is integration with a host processor?
TAS5822MDCPR uses an I2C bus for register-based configuration and accepts audio data over an I2S or TDM digital input. The I2C interface operates at standard 100 kHz and fast 400 kHz modes, making it compatible with virtually any application processor or microcontroller. Volume control, EQ coefficients, and power modes are all set via the I2C register map, so no analog potentiometers or external DSPs are required. This reduces the integration effort to writing a few I2C initialization sequences and significantly simplifies firmware for streaming audio devices.
When is TAS5822MDCPR a better choice than a traditional Class-AB amplifier for a portable 30 W stereo speaker?
In a portable 30 W stereo speaker running from a 24 V lithium battery pack, TAS5822MDCPR's Class-D efficiency of over 90% dissipates less than 6 W of heat at full output, versus 15 W or more for a Class-AB design with similar output power. Lower heat dissipation means a smaller heatsink, which can reduce enclosure depth by 10 mm or more. The 38-pin WQFN package also has a smaller footprint than typical TO-220 or TO-247 Class-AB output devices, freeing PCB area for battery management and wireless charging circuits in the same unit.
