Can you help me to test the specific delay time of input and output signals, using yourTAS5805 DOEM board, if we can meet our delay requirements, we will contact the agent for sample application and PCB production?

TAS5805M's input to output latency is about 11*Fs. For example, if the input sample rate is 48kHz, the latency is about 229uS.

That is to say, the delay of 96 kHZ will be twice that of 48 kHZ, right? Does TAS5103 also satisfy the formula of 11*FS? TAS5103 has simple internal structure and can be input by PWM. Does it have smaller delay or more exact delay formula?

If the input sample rate is 96kHz, the latency will be less. It's about 125us, based on our test results.

TAS5103 is a bit old device, I would suggest you choose some new devices instead.

Also, there is NO consistent formula for the latency of audio devices.
