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.

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.

6) Internal sample hold circuit.

7) Internal feedback resistors and capacitors for oscillator circuits.
