●Description
●Features
●Applications
●Product lineup
The Sound Processor with built-in record/play functions for cassette players, is suited for sound quality products such as,
BOOM BOX, mini- and micro-audio systems. It incorporates various functions ranging from audio source selectors to
preamplifiers at the front stage, preamplifier for cassette recording/playing, and a 2-wire serial bus.
BOOM BOX, mini-audio systems, and micro-audio systems.
1) Provides Surround and Bass Boost with the Soft-switching feature to reduce the shock sound at switching
2) Provides a specialized power supply terminal in a digital circuit, in order to set and maintain the state inside the IC by
3) Built-in preamplifier for cassette recording/playing allows for minimal external components, freeing up board space.
4) Arranges all I/O terminals to a single point and allows easy PCB routing.
5) Volume and Tone implemented with a resistance ladder circuit; achieving high performance with low noise and low
6) Energy-saving design resulting in low current consumption, by utilizing the BiCMOS process. It has the advantage in
(BD3401KS2)
the minute stand-by current.
