What
Beware - these need to be updated with actual assembled board. v2 includes sees top going bottom and vice versa.
Acquisition of a square/sine wave
Signal coming out of a cheap DSO, should be around square, 4MHz
Acquisition
Spectrum of a square wave at 125Msps
Changes from v1
- Remove i2c to something simpler - MCP40D17T
- Let user choose offset or not
- Check OPAMP capa to get a 60MHz cutoff
- BAV / MD0100 to be removed
- Putting the rp2040 under the board, to expose the beautiful art to users

Questions
How big is the ADC pHAT AFE ADC10080 PCB?
It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ADC pHAT AFE ADC10080 use?
68 parts, built around the LMH6629SD, OPA830ID, TPH2501-TR and ADG621BRM. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ADC pHAT AFE ADC10080 KiCad files?
From the kelu124/0xa5eded repository on GitHub, at the commit this page was made from: the board is hardware/v2.2/ADC_pHAT_AFE_ADC10080.kicad_pcb and its schematic hardware/v1/ADC_pHAT_ADC10080.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ADC pHAT AFE ADC10080 design in my own project?
Its repository states no licence, so its author keeps all rights: ask kelu124 before reusing the design.
