Renesas Technology’s Digital Amplifier IC Offers Adaptable Audio Tuning for Quality Sound and Has a Space-Saving Package, Aiding the Design of Thinner Flat-Panel TVs
The New High-Power R2J15116FP Digital Stereo Amplifier with an Internal 24-bit Audio Digital Signal Processor (DSP) Delivers a 15W Maximum Audio Output in a Compact 7mm x 7mm Package
SAN JOSE, Calif.– Renesas Technology America, Inc. has introduced the R2J15116FP, a compact, high-performance digital amplifier. The new IC accepts an IIS digital-audio signal input, performs processing with a built-in audio digital signal processor (DSP) unit, and then amplifies the result to deliver adaptively tuned stereo output to two speakers at up to 15 watts per channel. A key feature of the device is its space-saving 7mm x 7mm (body size) package, which fits into thinner LCD and plasma flat-panel TV sets, as well as into thinner computer monitors.
Reducing thickness while boosting audio quality
Consumer electronics manufacturers have learned that thinner flat-panel TVs gain consumers’ attention and sales, so they’re devoting considerable effort into finding smaller components and designing clever video system packaging. However, they understand that it makes little sense to gain a premium “thin†look if by doing so the sound the set produces becomes degraded because quality components won’t fit into the enclosure. The trend to thinner profiles and narrower screen frames necessarily places considerable restrictions on speaker placement and mandates the use of smaller, thinner, less-conspicuous speakers that make it more difficult to achieve good-quality sound and sufficient audio volume and presence. Yet demand grows for better audio as buyers show preferences for larger screen sizes. Simultaneously, TV manufacturers opting to maintain continuity with the screen sizes and profiles of current models are seeking ways to obtain precise tuning of sound production to suit different environments and set designs, and also to enable product-line expansions.
