BD3403FV, BD3861FS, BD3883FS

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.

BOOM BOX, mini-audio systems, and micro-audio systems.

BD3861FS

BD3883FS

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

4) Uses the BiCMOS process that achieves low-consumption current, which contributes to an energy-saving design.

5) SSOP-A32 and SSOP-B40 are used for the packages. Input pins and output pins are organized and separately laid

Reduced by 9.0 mW/℃ over 25℃, when installed on the standard board (size: 70×70×1.6mm) for (BD3403FV).

Reduced by 9.5 mW/℃ over 25℃, when installed on the standard board (size:70×70×1.6mm) for (BD3861FS,BD3883FS).

(to achieve high performance with low noise and low distortion).

Using the BiCMOS process, has the advantage in quality over the scaling down of the internal regulators and heat controls.

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.
