Description
Dimension (Units : mm)
BD3869F
BD3869F/S is a signal processor IC developed for
audio sound control of TV and mini-component
stereo. Volume and tone can be easily controlled
from micro-controller by two-wire serial control
(I2C-BUS). Front volume with loudness, rear volume
with trim, bass, and treble are integrated on a single
chip of SOP18 package (BD3869F) and SDIP18
package (BD3869S). Three ICs (Max.) can be used
simultaneously, due to the three kinds of I2C-BUS
slave addresses.
