WM8993ECS/RV 欧胜 说明CODEC with stereo speaker drivers and Class W headphone driverWM8993可提供一种超常的抗噪音能力，并带有接地参考的W类耳机驱动器，因此可极大地减少回放功耗，在正常使用的情况下可提供100小时以上的回放时间。WM8993还可提供强大的音频混合性能，使应用设备可支持极广泛的音频架构和使用场景，同时它的主动接地回路噪音抑制和直流偏压校正有助于防止降低耳机输出质量的爆破音和接地噪音。The WM8993 is a highly integrated ultra-low power hi-fi CODEC designed for portable devices such as multimedia phones. A stereo 1W/channel speaker driver can operate in class D or AB mode. Low leakage and high PSRR across the audio band enable direct battery connection for the speaker supply. Class W headphone drivers provide a dramatic reduction in playback power and are ground-referenced. Active ground loop noise rejection and DC offset correction help prevent pop noise and ground noise from degrading headphone output quality. Powerful mixing capability allows the device to support a huge range of architectures and use cases. A highly flexible input configuration supports multiple microphone or line inputs (mono or stereo, single-ended or differential). Fully differential internal architecture and on-chip RF noise filters ensure a very high degree of noise immunity. ReTuneTM Mobile parametric EQ with fully programmable coefficients is integrated for optimization of speaker characteristics. Programmable dynamic range control is also available for maximizing loudness, protecting speakers from clipping and preventing premature shutdown due to battery droop. The WM8993 is supplied in very small and thin 48-ball W-CSP package, ideal for portable systems  WM8993ECS/RV 欧胜现货订购热线： WM8993ECS/RV 欧胜 pdf datasheet(责任编辑：www.gongwin.com) |
