BH3864F

The BH3864F has been developed for use in mini-component stereo systems. Switching is done using a resistor ladder

to suppress DC offset at switching. Two-line serial control is available, and external three-line serial control is also pos-

sible. The package is a compact 24-pin SOP.

FApplications

Mini-and micro-component stereo systems, CD radio

cassette players and TVs.

FFeatures

1) Volume, tone, and dynamic bass boost control pos-

sible by a serial link to a microprocessor.

2) Left and right channel volume can be controlled inde-

pendently.

3) Resistor-ladder type volume control uses BiCMOS

process for low distortion and noise.

4) Dynamic bass and linked ALC are provided on chip.
