I'm putting together a product using the ADAU1702. I'm using one of these guys: Single Slew External Volume [Analog Devices Wiki], but find the documentation unfortunately lacking.
What does the slew rate entry actually mean in terms of a time constant (ms or samples or whatever); 1 is fast and 23 is slow is unfortunately not accurate enough for me (that's all that the documentation offers). Is there an equation you can give me?
Thanks very much
