Multimedia ICs Audio digital delay (KARAOKE echo) BU9252S / BU9252F The BU9252S and BU9252F are digital delays specifically for Karaoke systems. Each has an internal sample hold circuit, an 8-bit A / D and D / A converter and 2kB SRAM, and allows for the selection of one of eight delay times just by attaching an inexpensive ceramic resonator. A digital echo system can be formed by using either of these ICs together with the BA7725S or BA7725FS. Applications • Karaoke echo system Electronic circuits that require signal delays Features • 1) Internal digital delay circuit. 2) Internal 8-bit A / D converter. Sample rate. (14.22kHz when fOSC = 455kHz). 3) Internal 2k bytes data SRAM. 4) Internal 8-bit D / A converter. 5) CMOS design for low power consumption.
