Introduction

BD37033FV-M is sound processors for car audio. The functions are stereo input selector with single end 3 and ground isolation input 2, volume, 3-band parametric equalizer, loudness, 6ch fader volume, LPF for subwoofer, anti-aliasing-filter, Mixing volume. Moreover, “Advanced switch circuit”, that is ROHM original technology, can reduce various switching noise (ex. No-signal, low frequency likes 20Hz & large signal inputs). “Advanced switch” makes control of microcomputer easier, and can construct high quality car audio system.

Features

• Reduce switching noise of volume, mute, fader volume, bass, middle, treble, loudness by using advanced switch circuit [Possible to control all steps].
• Built-in input selector (single 3 / diff 2).
• Decrease the number of external components by built-in 3-band equalizer filter, LPF for subwoofer, loudness filter.
• And, possible to control Q, Gv, fo of 3-band equalizer and fc of LPF, Gv, fo of loudness by I²C BUS control freely.
• Built-in mixing volume and anti-aliasing-filter.
• Built-in anti-GSM-noise-filter.
• Package is SSOP-B28.
• Putting input-terminals together and output-terminals together can make PCB layout easier and can makes area of PCB smaller.
• It is possible to control by 3.3V / 5V for I²C BUS.
• AEC-Q100 Qualified.

Applications

• It is the optimal for the car audio.
• Besides, it is possible to use for the audio equipment of mini Compo, micro Compo, TV etc with all kinds.
