AD7656A/7A/8A and A-1's Absolute maximum ratings say “Vdd to AVcc is AVcc+0.7 to +16.5V”
I would like to know what mean about this spec.
Hi All ,
I have purchased AD7656A-1 ADC for my experimental work. I have configured it for SPI interface using zedboard.
Configuration is on Hardware. Using ALL data line A,B,and C. with internal ref selected.
But there is a problem that I am getting…
Dear ADI Technical Support,
We are designing a buffer to drive the analog inputs of AD7656A-1 (250ksps, 6-channel, simultaneous sampling, bipolar, 16-bit ADC). And we have following questions regarding its analog inputs.
1. What's the input resistance…
I have problems with AD7656A. It is connected in hardware mode, with internal reference, VDD/Vss +/-6V, input +/-5.0V max., input channels V1-V6, no STANDBY, CONVSTA+CONVSTB+CONSTSTC tight together, SPI interface, no daisy chaining.…
Hi - hope you can help.
Could you tell me AD7656 vs AD7656A-1 - are these devices pin-for-pin & Software compatible?
If not, how do they differ?
