BD3822FS - Rohm

BD3822FS NTSC-PAL Audio I/O

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.

Features

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, an.
