AK4552VT集成電路（IC）的編解碼器規(guī)格書PDF中文資料

AK4552VT屬于集成電路（IC）的編解碼器。由旭化成微電子株式會社制造生產(chǎn)的AK4552VT編解碼器編解碼器是用于通過壓縮和解壓縮來轉(zhuǎn)換數(shù)據(jù)的半導(dǎo)體器件。數(shù)據(jù)壓縮可提高傳輸速度并減少存儲空間。某些編解碼器提供高達(dá) 32 位的分辨率，并且分別提供多達(dá) 6 個或 8 個模數(shù)轉(zhuǎn)換器和數(shù)模轉(zhuǎn)換器。除三角積分調(diào)制外，還有 I2C、I2S、SPI、串行、HDA、S/DIF、PCM、USB、AC'97 和 SLIMbus 數(shù)據(jù)接口。

GENERAL DESCRIPTION

The AK4552 is a low voltage 24bit 96kHz A/D & D/A converter for digital audio system. In the AK4552, he loss of accuracy form clock jitter is also improved by using SCF techniques for on-chip post filter. Analog signal input/output of the AK4552 are single-ended, therefore, any external filters are not required. As the package is 16pin TSSOP, the AK4552 is a suitable for minimizing system.
