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.  
4) Internal 8-bit D / A converter.  
5) CMOS design for low power consumption.  
6) Internal sample hold circuit.  
2) Internal 8-bit A / D converter. Sample rate. (14.22kHz  
when fOSC = 455kHz).  
3) Internal 2k bytes data SRAM.  
7) Internal feedback resistors and capacitors for oscilla-  
tor circuits.
