I faced with the task to measure several inputs (0-10V analog) with galvanic isolation.
Using plain Google search (like '0-10V adc') I found several solutions like Linear Technology LTC1854/55/56 which has 8 inputs (single ended or 4 differential), -10...+10V input range (reference and supply voltage generated by the IC) which is very convenient. Galvanic isolation can be easily achieved by digital interface decoupling.
However this IC has SPI digital interface. I'd prefer I2C.
So I go to selector tools at several sellers and manufactures but no one has an option to choose wide input range. I can choose resolution, sampling rate, analog and digital power supply voltage... Anything! But I see no opportunity to filter ADCs with wide voltage inputs.
Can anyone suggest how can I search needed device? Maybe this parameter can be referred as "wide input range" or anything else? Maybe there are any selector tools allowing me to choose this option?
