Datasheet
Sound Processor Series for Car Audio
Sound processor with Built-in
2-band Equalizer
BD37503FV
●General Description
Sound processor which has built-in 4input selector and
2-band equalizer filter. And, loudness filter and 2nd-order
anti-aliasing filter which attenuate noise occurs at output
of DAC are available, either one by switching.
●Features
 Built-in differential input selector that can make
various combination of single-ended / differential
input.
 Reduce switching noise by using advanced switch
circuit
 Built-in ground isolation amplifier inputs, ideal for
external stereo input.
 Decrease the number of external components by
built-in 2nd-order anti-aliasing filter
 Decrease the number of external components by
built-in 2-band equalizer filter and loudness filter.
 A PCB area can be reduced and PCB layouts become
easy thanks to that signal flow is gathered to one
direction by arrangement of input and output left side
and right side separately.
 It is possible to control by 3.3V / 5V for I²C BUS serial
controller.
●Key Specifications
 Total harmonic distortion：
 Maximum input voltage：
 Common mode rejection ratio：
 Maximum output voltage：
 Output noise voltage：
 Residual output noise voltage：
 Ripple rejection:
 Operating temperature range
