I have a question.
Is this device fully differential input possible or SE only?
The PIN description seems to SE only.
Our customer's circuit can be simplified If differential is possible.
If it is really SE input, where is defined allowed voltage input range for analog ground input ? Datasheet says only about +/-21V on analog inputs. From pictures it looks like difference/differential…
The AD7616 is a SE input. But if you are looking for a differential bipolar input, I can refer you to AD7609. It is an 8 channel 18 bit Bipolar ADC. Do you have a specific feature that you are looking for an ADC? By the way , what application you are planning to build?
If it is really SE input, where is defined allowed voltage input range for analog ground input ? Datasheet says only about +/-21V on analog inputs. From pictures it looks like difference/differential amplifier on front of analog input. If it is really SE I assume that common mode voltage on input ( ground input ) is limited to certain range. What is allowed on ground pin ? +/-0.1V ? More ? Less ? Please make datasheet more specyfic otherway it is confusing.
Looks like Hiroshi is on vacation.
Can anybody from analog.com answer to this question ?
My mistake. That was question to Jonathan not to Hiroshi.Sorry.
Apologize for the late response. the ground voltage was not mentioned in the datasheet. I recommend limit it to +/-100mV.
Is it official Analog Devices statment ? Is it absolute maximum value ?What does it mean that you recommend +/- 100mV ? Did you talk to engineers responsible for this IC ? Or this is what you think and may be or may not be true ?How can I use IC with incomplete or wrong documentation for serious customer ?
I started also SR-137247-S8G5B1 ticket. Week gone , no response ( besides automated ).
Where is old good Analog Devices ?
