BD3869FS
BD3869FS is Audio Sound Controller IC manufactured by ROHM.
Description
BD3869F/S is a signal processor IC developed for audio sound control of TV and mini-ponent 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. Dimension (Units : mm) BD3869F
