I designed a headphone amplifier with LM4811 driven by a uC.
Although the data sheet extensively deals with the analogic performance of the device, no info is provided about the clock and data timing requirements.
Obviously some minimum clock period and maximum frequency rate applies but it is completely unknown if in the kHz range or in the MHz range. It is an important missing in the data sheet. My controller generates a 250ns wide clock pulse and everything seems to work but I have no idea if I am very near the device timing limit or may be confident on it.
Do a specification exists or the customer must search it by himself?
