Did we talk about this guy? It's not terribly new, but I'd never
heard of it. <br class="">

The interface is kind of funky, but here's the scoop:<br class="">
<br class="">
<i class="">The seven band graphic equalizer IC is a CMOS chip that divides
the audio spectrum into seven bands. 63Hz, 160Hz, 400Hz, 1kHz,
2.5kHz, 6.25kHz and 16kHz. The seven frequencies are peak detected
and multiplexed to the output to provide a DC representation of
the amplitude of each band. No external components are needed to
select the filter responses. Only an off chip resistor and
capacitor are needed to select the on chip clock oscillator
frequency. The filter center frequencies track this frequency.</i>
