Sound Processors for BOOM BOX / Mini-component Stereo
Sound Processors
with Built-in 3-band Equalizers
BD3403FV, BD3861FS, BD3883FS
No.10086EAT01
●Description
The Sound Processor has a built-in 3 Band Equalizer and can be controlled with a 2-wire serial. It is suited for a sound
quality design which incorporates various functions, ranging from source selectors, such as BOOM BOX, Mini-audio
systems and Micro-audio systems to preamplifiers at the front stage of the power amp.
●Features
1) High S/N, achieved by implementing 2-stage configuration of Front Volume and Rear Volume.
2) Provides surround and rear volume with Soft-switch to reduce a shock sound during switching functions(BD3883FS).
3) Volume and tone implemented with the resistance ladder circuit
(to achieve high performance with low noise and low distortion).
4) Uses the BiCMOS process that achieves low-consumption current, which contributes to an energy-saving design.
Using the BiCMOS process, has the advantage in quality over the scaling down of the internal regulators and heat controls.
5) SSOP-A32 and SSOP-B40 are used for the packages. Input pins and output pins are organized and separately laid
out so as to keep the signal flows in one direction which consequently, simplify pattern layout of the set board and
decrease the board dimensions.
●Applications
BOOM BOX, mini-audio systems, and micro-audio systems.

●Control signal specifications
1. Signal Timing Conditions
・Data is read on the rising edge of the clock.
・Latch is read on the falling edge of the clock.
・Latch signal must terminate with the LOW state.
・To avoid malfunctions, clock and data signals must terminate with the LOW state.
