Audio I/O Interface For DVD Recorder 32-Pin SSOP-A T/R

BD3822FS is 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. BD3822FS unify the board pattern by pin compatible, and can be used individually as a high-end and low-end model.

• 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)
• Low distortion (0.0015%) and low noises (2.3µVrms)(BD3824FS)
• Contains an ALC circuit, and can also be used as an RF output
• 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
• 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.
• BD3822FS and BD3824FS can be used with the same PCB board.
• I2C BUS data format of BD3822FS is upward compatible with BD3824FS, and can be used without changing the software.
• A system is employed, in which the waveform connected to the input (tuner, Front, Ext) is not distorted even in standby mode.
