CXA2559Q
Playback Equalizer Amplifier with Music Sensor
Description
The CXA2559Q is an IC designed for use in car
stereo cassette decks. Functions include playback
equalizer amplifier and music sensor into a single
chip.
40 pin QFP (Plastic)
Features
• Few external parts
• Small package (40-pin QFP)
• Same pin configuration as for the Dolby B-C type
NR system (CXA2561Q) and Dolby B type NR
system (CXA2560Q)
• Playback equalizer amplifier and music sensor into
a single chip
• FORWARD/REVERSE head select switch
• Mute function
• Music signal interval detection level can be set by
the external resistors/capacitors (2 modes).
• High-frequency cut-off of the music sensor circuit
can be adjusted by the external capacitance.
Applications
• Car stereo cassette decks
• Playback-only cassette decks
