my customer asks for the SNR that is to be expected with the following signal chain:
48 kHz input-signal ---> AD8250 ---> LTC6363 ----> AD7768-1
AD8250 is powered by +/-15 Volt.
The LTC6363 translates the up to +/-10V output from the AD8250 into a differential signal convinient for the AD7768-1.
I know that the effective SNR depends on input-signal amplitude, AD8250 gain and AD7768-1 configuration.
Which configuration will give the best SNR at 48 kHz, and which SNR is achievable?
Looking forward to your answers.
