Part Number : MSGEQ7
Function : Seven Band Graphic Equalizer
Pacakge : DIP, SOP 8 Pin Type
Manufacturers : Mixed Signal Integration ( www.mix-sig.com )
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 respons es. Only an off chip resistor and capacitor are needed to select the on chip clock oscillator frequency. The filter center frequencies track this frequency.
