Double?abbey road d enfer said:You should increase the width of the ground tracks; it makes routing somewhat more difficult, but that's what double-sided is for.
In all the datasheets and on the evaluation board of the 1646 pin 1 is always connected to GND. Why is that?abbey road d enfer said:I noticed Pin 1 of the output connector is connected to audio ground; should be connected to "earth".
I've used this circuit for other projects. The metering got no integration time or smoothing. You're right, it is quite annoying. I thought about a seperat project, building a VU meter using a arduino / microcontroller.abbey road d enfer said:Have you breadboarded the LM3914 circuit? I'm not sure you'll find it satisfactory...
Any suggestions?
