Other Parts Discussed in Thread: ADS1298
Hello,
I'm working with the ADS1298R powered by 3V on AVDD and 2.4V on DVDD and connected to a 2.4V powered MCU.
Referring to the datasheet the High-level Input Voltage is : 0.8*VDD < Vih < DVDD + 0.1. How I should understand this ? Should I ensure to have a minimum of 2.5V (DVDD+0.01) on my Input signal to be sure that the ADS1298 will understand a "1" ? Or the "min" and "max" are only a range where we should be ?
In the first case my input be be higher than the DVDD power supply of the ADS1298, is that ok ?
I also have the same question regarding VIL min and max
Thank you in advance for your answer and time !
Best regards
