### 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?...

### Adding offset voltage to sensor signal

I have a pressure transducer outputting 0-5V which is sampled by an ADC with a 0.5V minimum input voltage. I need to offset the sensor output voltage by a fixed voltage of 0.5V. I've looked at an op ...

### Offset an input voltage of -2.5V - 2.5V to 0V - 5V? [duplicate]

I have a circuit input which provides a voltage range of negative 2.5 volts to positive 2.5 volts. How do I change this so the output voltage is 0 - 5 volts? simulate this circuit – Schematic ...

### A question on factors affecting the offset removal of an opamp circuit

I will use a function generator module which outputs 0-1V sine-wave for frequencies of interest from 0.5Hz to 30kHz importance. So my input will be 0-1V sine wave but I want to obtain an AC sine wave ...

### How to compute DC offset of analog circuit?

I have an analog circuit which has an input voltage range Vin of 5V - 10V and output voltage Vout. One can assume that the circuit has been simulated and a DC sweep of Vin with a range from -10V to +...
