Can someone explain this gain & offset op-amp circuit?

I'm having trouble understanding the circuit in the photo below. I know that it's a gain and offset amp designed to convert 0-2.5 V range to +/-10 V range (hence it has a gain of 8 and an offset of -...

Piezo into 0-5v ADC, with offset center voltage?

I want my piezos to have a center voltage at 2.5v for a 0-5v ADC input on Atmega328, so it can sense force in both ways - one way would be >2.5v and the other will be <2.5v. Will this circuit work?...

What is meant by “adjustment of the output gain and offset” of a Force Sensitive Resistor interface circuitry?

A FSR (Force Sensitive Resistor) is a sensor which lowers its resistance when there is force upon it. At idle state (no push force) it has a high resistance (~ MOhms) Interlink Electronics has ...
