The FR6391 is a CMOS IC that has a microphone peripheral circuit and an echo generation circuit for karaoke use, on a single chip.

FEATURES


● High-performance digital echo circuit using 44-Kbit RAM

● A mic amplifier with an ALC makes it possible to handle overload input, and the ALC operating voltage can be externally set to the desired value.

● Built-in mic volume, echo volume, and feedback volume

● Internal micmixing amplifier

● The clock has an internal current control-type oscillation circuit, and the generation of unnecessary oscillation can be prevented because the clock does not affect anything external to the unit.

● Internal Auto Reset circuit that functions when the power supply is turned on.

● MIC Volume, Echo Volume, and Feedback Volume are controlled by I2C Bus or DC control. (Delay Time is only I2C Bus)

● 5V single power supply

● Package Type- SOP 28

                              - QFN 28

APPLICATIONS


● Wireless Microphone

● Karaoke System

● Consumer Audio Applications

● Car Entertainment System
