Hi team,
I have a customer design in AMC1306 and have some questions.
1. How can we know how much the ripple voltage value by the PSRR value? And what if the ripple voltage over this value, will it cause any side affection?
2. About inside AMC1306, VCC,Data,CLK. Is there any chance that may effect VCC because of Data and CLK ground circuit (RC filter) ?
Hi Len,
PSRR is specified in the datasheet - our power supplies are very robust.
The nature of the power supply ripple will determine what happens to the output. For example, if the ripple is so severe that the high side supply voltage specification is no longer met, the device may temporarily shut down. Smaller ripples, severe enough to violate the PSRR specification may result in a temporary "offset" on the output.
I don't fully understand the second question - however VCC should not be affected by an RC filter on Data or Clock.
