BD3824FS

TECHNICAL NOTE Video/Audio Interfaces for TV and DVD Recorders NTSC-PAL Audio I/O Interface for Recording/Playing BD3822FS, BD3824FS ƔDescription BD3822FS and BD3824FS are the audio selectors with internal input selector, gain amp, ALC and power save ON/OFF functions. BD3822FS contains the 1/2 power compression amp for level meter and 2ch volume. BD3824FS contains the line amp. BD3822FS and BD3824FS unify the board pattern by pin compatible, and can be used individually as a high-end and low-end model. ƔFeatures 1) Low distortion (0.0015%) and low noise (3.2μVrms) by using a resistance ladder type circuit for volume. Shock sound in switching is also reduced (BD3822FS) 2) Low distortion (0.0015%) and low noises (2.3μVrms)(BD3824FS) 3) Contains an ALC circuit, and can also be used as an RF output 4) Best suited to energy-saving design by low current consumption by using the Bi-CMOS process; compact regulator in the set, being advantageous to heating in terms of quality 5) SSOP-A32 is used for package. The PCB layout can be easy and the area of PCB is reduced by putting sound input terminals together, and output terminals, too. 6) BD3822FS and BD3824FS can be used with the same PCB board. 7) I2C BUS data format of BD3822FS is upward compatible with BD3824FS, and can be used without changing the software. 8) A system is employed, in which the waveform connected to the input (tuner, Front, Ext) is not distorted even in standby mode.
