( / 15 )
The M65845AFP is a CMOS IC built-in Digital Echo function with microphone
peripheral circuits for "Karaoke" equipment packed in a single chip.
It is suitable for "Karaoke" equipments such as Video CD Player,Mini Stereo,
CD-Radio cassette,TV or VCR.
Being pin compatible with the M65845FP,the M65845AFP is suitable for
upgrading the series.
Supply voltage rangeVcc=4.5~5.5V
Rated supply voltage Vcc=5V
RECOMMENDED OPERATING CONDITION
High performance digital echo circuit thanks to 16Kbit
memory
Two microphone-mixing lines,vocal cut circuit,digital echo, and
line-mixing amplifier are contained,enabling single-
chip package of microphone peripheral circuit of "Karaoke"
equipment.
ALC-equipped microphone amplifiers permit excessively
high-input. ALC operating voltage can be set as desired.
Vocal cut circuit of complete stereo construction
