ADG5208: THD specifications missing at the ADG520x family

Q

For Hi-Fi Audio, THD is an important figure and I am looking for a device
ideally with a maximum THD of 0.002% THD+N across the 20Hz - 20kHz frequency
range. Can you please advise whether this information is available for any of
these devices?

A

The ADG54xx parts are designed for low Ron and low Ron Flatness, which gives
good THD+N for the parts. The ADG52xx parts are designed for low Charge
injection and low capacitance. This increases the Ron and Ron Flatness and
affects the THD+N of the part. As the ADG52xx parts are not typically used in
applications where THD+N is a critical spec, they have not been specified for
it.
You can see the difference between similar parts by comparing the ADG14xx with
the ADG12xx.
