Digital Echo 16-Pin SSOP-A T/R

The BU9253FSis 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.

• Echo mixing ratio is adjustable with a DC voltage.
• A second order LPF can be configured with the internal amplifier and an attached capacitor and resistor.
• Delay time of 131ms. (when fCLK = 357kHz)
• Internal mute function.
• Single power supply (5V).
• Power dissipation Unit is mW
• Operating temperature: - 10 °C to + 70 °C
