I am trying to design a circuit that has the function -k*1/x. I'm looking into your multiplier ICs, could you help me select the correct IC for this function? An app note if available would be great too!
My power rails are +/-5V, my input voltage range is from 0.4V to 2V.
I was looking on some of our multipliers/dividers product and found a few devices that can cater your supply rails requirements. AD834, AD835, AD538 and AD539 however, there are no exact configuration on how to achieve your transfer function w=-k*1/x on these devices datasheet. AD633, however. has shown one way to achieve this together with AD711. Unfortunately, AD633 operates on +/- 8V minimum supply. AD835 could be a good candidate for this but can't surely say it perfectly fit without testing or running some simulation. I laready forwarded your question to the product owner of these devices to further support your question.
