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.
