About Infineon soundbar solutions

Soundbars are used to generate crystal-clear yet powerful sound as a companion to flat-panel TVs. There are usually multiple speakers in a soundbar, that can generate from basic stereo sound up to immersive 3D sound. Despite the long shape of soundbars, the usable PCB area for a sound bar system is actually quite limited. Hence solution compactness, power density, high efficiency operation, less heat, or idle power generation are very important features to keep in mind when designing a soundbar.

Infineon's versatile class D amplifier solutions are very ideal for soundbar designs. The MERUS™ multilevel class D amplifiers work with smaller output filters and have only 1/10th of idle power consumption compared to traditional class D toppology, which makes them perfect for tweeter channels in the soundbar. The MERUS™ multil-chip-module class D amplifier family has very low Rdson and very high full load efficiency, making them ideal to power subwoofer channels in the soundbar systems.

The PSoC™ 4000 family delivers the industry’s best capacitive-sensing technology, CAPSENSE™, to implement buttons, sliders, and proximity sensors.

We recommend using either PSoC™ 4000S or PSoC™ 4100S, depending on how many IOs/touch buttons are needed. The PSoC™ 4000 family is a cost-optimized, entry-level family of Arm® Cortex®-M0 and M0+ microcontrollers. The PSoC™ 4100 family adds intelligent analog integration through programmable analog blocks. Programmable analog blocks include analog-to-digital converters (ADCs), digital-to-analog converters (DACs), low-power comparators, and operational amplifiers (opamps). The PSoC™ 4100BL includes an integrated Bluetooth® Low Energy radio and subsystem.

If you require a metallic overlay for an HMI solution PSoC™ 4700S with noise immune inductive- and capacitive-sensing user-interface is the best choice. The PSoC™ 4700 family adds advanced sensing technologies to Sense Anything including advanced capacitive sensing, inductive sensing, heart-rate sensing, and more. These advanced sensing technologies leverage specialized analog blocks in the PSoC™ 4 portfolios to deliver innovative solutions to next-generation designs.
