With major consumer electronics brands using Class D amplifiers to design TVs and home audio with slim, high-output, high-fidelity audio, STMicroelectronics (ST), a leader in audio IC technology, is introducing a new 50W+50W stereo Class D amplifier IC, the new product has extremely high energy efficiency and requires less external components, giving designers a competitive advantage. This article refers to the address: http:// The introduction of the TDA7492 extends ST's analog input Class D amplifier family to higher-end applications. The series currently includes 3W-, 5W-, 10W-, 20W-, 25W, and 50W--channels. These products are package-pin compatible, allowing developers to expand their designs to meet multiple market demands. The TDA7492 is the first 50W+50W amplifier on the market with a sixth-generation BCD6S (bipolar/CMOS/DMOS) advanced process that supports monolithic integrated analog, logic and high voltage functions. Compared to other Class D amplifiers, STMicroelectronics' BCD6S process creates higher chip area energy efficiency ratios while reducing crosstalk and improving sound quality. In addition, the BCD6S integrates NMOS and PMOS complementary transistors in a high power output circuit, eliminating the bootstrap capacitors and cathode load diodes required for older processes. This approach simplifies design, saves PC board space and reduces material costs. ST's TDA7492 has a distortion (THD+N) of less than 0.01%, providing listeners with a high-quality listening experience. The built-in output filter circuit minimizes external audio filter requirements and integrates standby and mute functions. . The IC is optimized for EMI radiation, and the low EMI feature further simplifies the Class D amplifier design, which is smaller than conventional A/B circuits and has higher audio power. Other features include external synchronization and support for high-performance multichannel Class D amplifiers that integrate multiple discrete ICs. On the top of the Power SSO-36 package for improved heat dissipation, there is a bare thermal pad that allows the designer to connect a simple heat sink. The TDA7492 is now in volume production.

Class D amplifiers use switching operation with an energy efficiency of approximately 90%, compared to 50% for conventional A/B amplifiers. Because the power lost by the amplifier is dissipated as heat, the Class D amplifier operates at a lower temperature, so the size and cost of the D-stage amplifier's heat sink is significantly reduced compared to Class AB devices of the same class, even in some Application, no need for a heat sink at all. In addition, Class D amplifiers consume less power at a given output power, so smaller power supplies can be used, resulting in reduced size, reduced weight, and cost savings. Currently, suppliers of high-quality audio equipment such as high-fidelity amplifiers, MP3 player docks, home theater systems, and high-definition televisions are using Class D amplifiers to provide ultra-thin, lightweight designs for the highly competitive consumer electronics market.
