Building the AK5388 ADC breakout board
“Honey, the package you’ve been waiting for from Hong Kong is by your computer,” said my dear wife shortly after I got home from work on Friday. Even better, a few minutes later she suggested that I spend the evening … Continue reading

Trying out Itead Studios’s PCB prototyping service
I’m working on building a breakout board for the high-performance AK5388 audio ADC. In my last post, I revised the schematic to help with the PCB layout and test-fit the key components on a printout of the board. The next … Continue reading
AK5388 ADC breakout board update
For the last month or two, a breakout board for the AKM Semiconductor AK5388 analog-to-digital converter has been my main project. Here’s an update on where it stands. When I last posted about the board, I was waiting for parts … Continue reading
PCB routing techniques for ADCs
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
PCB layout for the AK5388 ADC breakout board
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
gedasymbols.org is a great part of using gEDA
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
AK5388 audio ADC breakout board design
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
Choosing a high-performance audio ADC
As I discussed two weeks ago, it is time to refocus my efforts on the DSP-based ham radio project that started this blog. Let’s take a look at the architecture I had in mind originally: This is a popular topology … Continue reading
