BD3402KS2
Sound Processors for BOOM BOX / Mini-component Stereo
Single Power Supply Sound Processors
with Built-in Pre Amplifier for Tape Recording
and Play Back (With Integrated 2-/3- band Equalizer)
BD3401KS2,BD3402KS2
No.10086EAT03
Description
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.
Features
1) Provides Surround and Bass Boost with the Soft-switching feature to reduce the shock sound at switching (BD3401KS2)
2) Provides a specialized power supply terminal in a digital circuit, in order to set and maintain the state inside the IC
by the minute stand-by current.
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 distortion
6) Energy-saving design resulting in low current consumption, by utilizing the BiCMOS process.
It has the advantage in quality over the scaling down the power heat control of the internal regulators.
Applications
BOOM BOX, mini-audio systems, and micro-audio systems.
