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 f
OSC
= 455kHz).
3) Internal 2k bytes data SRAM.
