Description

The BU9252S and BU9252F are digital delays specifically for Karaoke systems. Each of BU9252S 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 BU9252S together with the BA7725S or BA7725FS.
