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.
