While giving Differential input to the ADC Part No-AD7688,what are the input conditons need to take care.Please send me if you are having reference design.
VIO range is 1.8V to Vdd, but Timing Specification is guaranteed with 2.3V to 5.5V or VDD+0.3 V. Please refer to Page5.
Can you guaranteed with 1.8V to Vdd? If not, please let me know about the below specification with VIO=1.8V.
We're facing a issue that the analog input is instability below.
CH4 is IN+. CH3 is SDO.
Actually the driver amp is OPA197 (Ti), we recommend ADA4084-1 instead of Ti.
But the customer say if the instability is not improved within this week, he may…
I have a question from our customer about AD7688 ENOB performance.
In the datasheet page-4, the vref input voltage range is described as 0.5V to VDD+0.3V.
Our customer is going to use 1.0V for vref voltage.
And they needs 14bit ENOB in this…
I have a question from a customer about timing parameter of AD7688.
The VIO range is described as 1.8V to Vdd+0.3 in page4 of the datasheet.
But "specified performnace" range is 2.3V to Vdd+0.3V.
Our customer wants to know the I/O…
