Instead of the 40 Hz source I would input the Which supply voltage range should the OpAmp have? I mean the output should only be in the range of Or does it have to cover the sum of the two input voltage maximum and minimum i. Are there any constraints regarding the DC-bias supply V? Does it matter whether I would use a Linear Voltage Regulator or a Voltage Reference as long as the rated current of the device is not exceeded?
One thing you could do is use a summing amplifier to scale and offset the input signal simultaneously. This does invert the output, so you'd have to follow this amplifier with a -1 gain stage. If you plug in the values chosen somewhat arbitrarily , you'll see how the math works out. The important point to realise in this inverting amplifier op-amp configuration is that the feedback adjusts the output to make the two inputs equal. Since the non-inverting input is at 0 V the inverting input will be at zero as well.
It seems strange but your op-amp will never see the input voltages. The two inputs will normally be extremely close to zero volts. You have the luxury of having higher voltages available. With something like 10k in there you'll only be pulling a little over a milliamp.
All that is required is that the source voltage is stable. Not always. Read the datasheets carefully. You may not need to go to all that trouble. A potential divider with a little bias can do what you require without any op-amp in many cases. You haven't told us the source impedance so be careful that this circuit doesn't load it too much. If it's a problem scale all the resistors up, for example, by ten. Sign up to join this community. The best answers are voted up and rise to the top.

One that is rail to rail since you don't have a split supply. You need to make sure that that output can drive to either supply, otherwise you'll see clipping on the output. Whether it is realized or not, there are more common electronic devices that utilize summing amplifier circuits as they perform their other primary functions.
Any time one or more signal or voltage is being input to a device and the device only has one output, the circuit within the device is a summing amplifier circuit. These types of circuit formats are also used in devices that are related to different types of currents. Both AC and DC currents can be input to the amplifier circuit to output a constant voltage or signal. Alexis W. Last Modified Date: June 08, Is Amazon actually giving you the best price?
