KARAOKE echo IC

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 compone 1) Echo mixing ratio is adjustable with a DC voltage.\n2) A second order LPF can be configured with the internal amplifier and an attached capacitor and resistor.\n3) Delay time of 131ms. (when fCLK = 357kHz)\n4) Internal mute function.\n5) Single power supply (5V).;
