BD37503FV
Sound Processors with built-in 2-band Equalizers
Sound processor which has built-in 4input selector and2-band equalizer filter. And, loudness filter and 2nd-orderanti-aliasing filter which attenuate noise occurs at output of DAC are available, either one by switching.
For Automotive usage, please contact Sales.

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.
