I am buying a 0.01% resistor one. Good price for use with a Wave I/O I2S input module

Thanks for the prompt.
Could be very interesting ...
Sure am glad they are doing the soldering!!!
Is there some way to correct for the errors? One part in 10,000 is going to give a little more than 13 bit accuracy.

You can laser trim the chip as in the case of Krell with the PCM63
Are you planning to do laser trimming?

No, hence 0.1% when the price is reasonable.
There is actually another variable; 0.01% resistors of what kind. Vishays will be best but the cost!!!!!!! And you can have better than 0.01% with 1ppm tempco.
Read about that. Would be interested to learn how your build performs, if you can report back?

Color me dumb, but I cannot find the site that actually sells the product..........
Todd - it states that the modules will become available in the linked webshop in due time, likely November or December.
The design piqued my interest.... I was on the site, didn't realize it wasn't ready for prime time.
