I have a problem using a IC MSGEQ7.
When i connect a constant 63Hz signal to the input the IC responds to it, but as you can see in the print screens of my scope, the output is not constant. It fluctuates over a range of 800 mV while it should be constant. When i zoom out on the image, you can see that there is a returning pattern in the fluctuations.
Dous someone have a clue what could be the problem here?
Channel 1 is the output signal. You can see the 63Hz and the 160Hz band. I do not read the 5 other bands.(only 2 strobe pulses) On channel 2 you can see the reset signal.(every 1000µs)
Sorry for the poor englisch
