【选型】平板电脑上音频电路的小信号晶体管、肖特基二极管、和ESD瞬态电压抑制器选型推荐
平板电脑的音频电路中,Central推荐使用小信号晶体管(CMUT5088E/CMUT5087E/CMPT3904E/CMPT3906E/CET3904E/CET3906E);肖特基二极管(CMASH-4/CMLSH-4/CTLSH01-30L)和ESD瞬态电压抑制器(CFTVS5V0LC/CTLTVS12),对小信号有足够的响应能力,并且有优异的整流能力和ESD瞬态电压防护能力。
【方案】平板之Central Semiconductor(中央半导体)型号推荐
描述- 纤薄的平板电脑设备需要其半导体元件封装比之前薄75%,而不影响电气性能。 同时,平板电脑设计人员被要求提高整体能源效率,并保护敏感的集成电路免受有害的ESD瞬变损害。 面对这些设计挑战,Central Semiconductor(中央半导体)提供低成本、高能效的分立元件和全面ESD保护产品的完整解决方案。

介绍蓝牙音频模块中SBC、AAC和aptX的区别
众所周知,蓝牙音频模块中我们常见的音频解码格式是用的SBC,这个格式是蓝牙音频传输协议中强制规定的格式。在实际体验中,它的音质会稍微弱于AAC解码格式,AAC是一种高压缩比的音频解码算法,而apt-X是CSR独有设计的一种无损音频解码算法。本文中FEASYCOM来给大家介绍蓝牙音频模块中SBC、AAC和aptX的区别,希望对各位工程师有所帮助。
