PCB layout is fun, especially when you are trying to eke the best performance out of a component. Last week, I finished the PCB layout for the AK5388 analog-to-digital converter (ADC) I chose for my digital ham radio transceiver project. … Continue reading
I had some time to myself this weekend and was able to get the AK5388 breakout board routed. The board carries an AKM AK5388 audio DAC, which has 24-bit output and up to a 123 dB signal-to-noise ratio. My plan … Continue reading
I’ve joined up as a contributor to gedasymbols.org. This great resource, run by DJ Delorie, hosts schematic symbols for gschem and footprints for gEDA’s layout software, PCB. A search engine helps locate symbols and footprints, and gedasymbols includes links to … Continue reading
Cleveland has had wind gusts of over 50 miles per hour (80 km/h) today, and my antenna is still up. Hopefully that bodes well for the coming winter.
A few weeks ago, I picked the AKM Semiconductor AK5388 as the analog-to-digital converter for my receiver design. This high-performance audio DAC has a 24-bit output with up to 123 dB signal-to-noise ratio (A-weighted). I hope that the narrower bandwidths … Continue reading
