KARAOKE echo IC

BU9253AS / BU9253FS / BU9255FS

The BU9253AS, BU9253FS and BU9255FS are single-chip ICs that contain all the components needed to configure

a KARAOKE echo system: an A / D and D / A converter, SRAM, LPF, and mixer for mixing source signals. With

these ICs, an echo function can be configured easily and with minimum external components.

Applications

•

KARAOKE functions for portable stereo sets, mini com-

ponent stereo sets, video CDs and DVDs, etc.

Features

•

1) Echo mixing ratio is adjustable with a DC voltage.

2) A second order LPF can be configured with the

internal amplifier and an attached capacitor and

resistor.

3) Delay time of 131ms. (when f^CLK= 357kHz)

4) Internal mute function.

5) Single power supply (5V).
