The TPA3100D2 delivers up to 20W of continuous stereo output power per channel without the need for external heat sinks. Applications typically range from 27-inch DTVs with a high demand for small form factor and audio fidelity. The TPA3101D2 is pin-to-pin compatible with an output power of 10W per channel, primarily for DTVs with less than 27 inches of screen. Both devices are capable of driving nominal loads as low as 4 ohms.
The TPA310xD2 family of devices delivers superior performance while reducing the number of external components required, which not only significantly reduces overall system cost but also helps develop smaller, more stylish end products. For example, the TPA3100D2 is 92% efficient when driving 8Ω speakers, eliminating the need for external heat sinks. The TPA310xD2 family of devices has a wide operating voltage range of 10 to 26V, which simplifies power requirements and allows operation at LCD backlight voltages. In addition, thanks to its thermal and short-circuit protection and automatic recovery options, it ensures excellent reliability and proven robustness.
Both of these amplifiers significantly simplify and speed up the design effort, allowing designers to focus more on introducing differentiated products and accelerating time-to-market. For example, because of the pin-to-pin compatibility of the TPA3101D2, people using the device for TV design can easily upgrade their system to a TPA3100D2 that delivers 20W of output power without spending too much time. The pinouts of the various devices are optimized to significantly reduce EMI and make panel layout easier. In addition, the reference layout has been tested to comply with Federal Communications Commission (FCC) Part 15 Class B and European Certification (CE) CISPR 22 for anti-EMI requirements.
The TPA310xD2 family of devices is a new addition to TI's full line of high-performance analog and digital signal processor (DSP) products, ideal for home entertainment audio systems such as PCM1850 multiplexed input audio data converters, stereo audio analog-to-digital conversion , AureusTM audio DSP platform, Class D and PurePath DigitalTM audio amplifiers, and audio clocks such as CDCE906. TI is committed to providing silicon, software, system expertise and related support for the entire audio signal chain to help customers accelerate their time to market.
The TPA3100D2 and TPA3101D2, both Class D audio power amplifiers are available now and are available now from TI and its authorized distributors in a 7 mm x 7 mm 48-pin leadless quad flat (QFN) package. In addition, device versions in the 48-pin TQFP package will be available soon. The suggested retail price for the TPA3100D2 and TPA3101D2 is $3.50 and $3.10, respectively, in 1,000-piece quantities.
