ADuM5000 noise characteristics

flatmax on Sep 19, 2019

I wanted to use the ADuM5000 in a design for audio.

Are there and noise characteristics for <200kHz shown anywhere ?

thanks

Matt

The ADuM5000 has Viso output voltage ripple from the dc to dc high frequency switching frequency of 180MHz. It also has an output noise from the frequency of 600kHz of the PWM feedback control of the Viso output voltage, as can be seen in datasheet figures 10 & 11. It is possible that there is noise at lower frequency < 200kHz but we don't have any data on this.
