{"title":"Graphic Equalizer Display Filter - MSGEQ7","handle":"graphic-equalizer-display-filter-msgeq7","url":"/products/graphic-equalizer-display-filter-msgeq7","description":"The MSGEQ7 is a CMOS graphic equaliser IC that divides the audio spectrum into seven frequency bands: 63 Hz, 160 Hz, 400 Hz, 1 kHz, 2.5 kHz, 6.25 kHz, and 16 kHz. Each band is peak-detected and multiplexed to provide a DC output representing the amplitude — ideal for driving LED audio visualisers and spectrum analysers.\n\nRequires only two external components (one resistor and one capacitor) to set the on-chip clock oscillator. The multiplexer is controlled via reset and strobe pins, allowing readout with just two I/O pins from your microcontroller.\n\nKey Features\n\n\n7-Band Frequency Analysis – 63 Hz, 160 Hz, 400 Hz, 1 kHz, 2.5 kHz, 6.25 kHz, 16 kHz\n\nMinimal External Components – Only one resistor and one capacitor needed\n\n3.3V or 5V Operation – Supply range of 2.7–5.5V (best performance at 5V)\n\n20 dB Gain – Built-in signal amplification\n\nLow Power – Less than 1 mA typical quiescent current\n\n2-Pin Multiplexer Control – Reset and strobe pins for simple readout\n\nVariable Decay Time – Controlled by multiplexer readout rate (10% decay per read)\n\n8-Pin DIP Package – Breadboard-friendly form factor\n\n\nSpecifications\n\n\nIC – MSGEQ7\n\nTechnology – CMOS switched-capacitor filters\n\nSupply Voltage – 2.7–5.5V\n\nQuiescent Current – <1 mA typical\n\nPackage – 8-pin DIP\n\n\nIdeal For\n\nLED audio spectrum visualisers\nMusic-reactive lighting projects\nPortable audio equipment\nArduino and microcontroller audio analysis\n\n\nResources\n\nMSGEQ7 Datasheet (PDF)\nManufacturer Product Page\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":12775,"title":"Default Title","sku":"SF-COM-10468","price":11.68,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":1175,"option1":"Default Title"}]}
