What is the Gain Error of PCM4220?

Other Parts Discussed in Thread: PCM4220

Hi,

I haven't found the gain error specification of PCM4220 in the data sheet. Does it have this spec? Or approximately what order the number is? 0.1%, 1%, 10%?

Currently I'm designing the calibration circuit for PCM4220. I have to know what calibration range the circuit have to cover.

Thanks.

Hello Chi-Yang,

I just wanted to let you know that I'm still looking into this for you. I'm currently in contact with the design team and we are still trying to track this down for you.

Thank you for the patience,

Nate

Hello Chi-Yang,

Unfortunately we don't have this data available as this is a DC spec and these parts are designed for AC applications. Speaking with the members of the team we would expect these parts to have a gain error around 1% but you should verify that for your design.

Best regards,

Nate
