常备现货 FR6391 PCT普诚 回声处理器IC
DESCRIPTION
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.
● 5V single power supply
APPLICATIONS
● Wireless Microphone
● Karaoke System
● Consumer Audio Applications
● Car Entertainment System
