Audio Frequency Analyzer Chip – MSGEQ7

• Divides the audio spectrum into seven bands
• Frequencies are peak detected and multiplexed to the output to provide a DC representation of the amplitude of each band
• Low Power Consumption
• On Chip Ground Reference

The Audio Frequency Analyzer Chip – MSGEQ7 is 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.

Features:

• 3.3 or 5 Volts Operation
• 20 dB of Gain
• On Chip Oscillator
• Output Multiplexer
• Variable Decay Time
• 8 Pin DIP Package
