Can anyone nudge me in the right direction for a solution - from some searching it seems Op Amps are a routes but I can't find the right language/search terms to reveal a solution...

[15:29] Level shifting I've found seem to focus on digital re-scaling... ie on/off while I want the full range of voltages [15:34] The resistor values in that rescaling example are rather low, you can get away with making them a lot higher if current consumption is an issue. [15:34] Ohh linked from your suggestion was something that does 0 - 5v to -5 - +5v by combining the learnings from these designs I should be able to get somewhere... [15:34] https://electronics.stackexchange.com/questions/3042/converting-scaling-a-voltage-range-0v-5v-to-5v-5v?rq=1 [15:35] Helpful thought re resistors - current not so much of an issue, but accuracy is, so I guess I'll need very high tolerance resistors... [15:37] Yes, lower values can help a bit with accuracy as the bias current of the opamp inputs has a smaller effect. Not really a problem with modern opamps though.
