Can I just confirm what would be required to make a complete ADC module that would provide analog > ADC > USB > PC?

- AKA102B ADC module
- Input buffer (and power supply)
- 2x DAC power supplies (3.3 and 1.2v)
- I2S to USB module
- Case, connectors etc

Is that all?

I will be using at least two ADC ín my application. These will need different I2C adresses. Could you include jumpers to choose I2C adresses? Four addresses should be enough?

There are 'jumpers' to select these. Up to 2 ADCs can be directly addressed by an external controller for up to 4 input channels. More channels possible by extended addressing or using other techniques

AKA102B Pre-order

This the latest preview. Very much close to finishing the layout.
Labels "A, B, C & D" are link pads for different Fs in hardware mode. More links underneath the board for mode, address select, etc

Order form can be found here:
AKA102B GB

I will need order for at least 24 boards to progress further.
Limited stock of 9102 chips - latest RevC type.
Lead times for chips ~6-8wks
Priority for those who have registered interest earlier. Please check and update accordingly.
Request for payment will be made when boards are ready for fab
More work to be done ...
Thank you for your support :)

Wouldn't it be wise to include ADM7150s for the 3.3 V rails for convenience? I doubt that there is a better spec'd regulator in foreseeable future. (didn't found a corresponding appropriate DIY adapter as yet)

The pic show in an earlier post has a AKR75 3-Term Reg connected- based on ADM7150, available soon. just waiting to complete a 1.2V version:

--- You can also use 3-term types with connections as shown. Makes it very straightforward and you can experiment with different types rather than a fixed on-board one

Preview AKR75 3.3V 3-Term regulator.
Priced at USD 35 but those who are getting the ADC module will get discounted offer at USD 25 for use with AKA102B only and can be shipped together (fully assembled and tested). You will need one for each AVCC section but has sufficient drive if you wish to use only one AKR75 and share power with both the L/R channels. Also suitable for the oscillator section. Optimized and efficient design. Thermal paths on ground plane itself - No bulky heatsinks required for use with AKA102B or other low power loads

Also suitable for your other projects.

Separate GB now open here:
AKR75 GB
