Hello,
regarding the CDCUN1208LP. I see a min slew rate of 6500V/s in the datasheet. For 3.3V that's about 0.5ms. Is that the minimum rise time? The datasheet is confusing because it states 6500V/s is the minimum slew rate, which would mean that VDD needs to rise faster than 0.5ms. Please clarify, thanks.
Hi Mark,
That's right. It needs to be faster than that. But if you look at footnote 2 of 6.3, you can go down to 5000V/s when your ambient temperature is above 0 Celsius. This is all true in pin mode.
If you are using I2C or SPI mode, then this doesn't apply if you use Reset bit after ramping the supply.
Best,
Asim
