The schematic in Figure 1 is a common summing amplifier with multiple inputs and one single-ended output. It is a variation of a standard inverting amplifier. Point X is a virtual ground and is ...

When you need to use multiple sensors with analog outputs in a measurement system, each sensor may respond differently to a known stimulus. As a result, you'll probably need to calibrate the system.

The use of Operational amplifiers can improve the performance of a wide variety of signal processing circuits. In rectifier circuits, the voltage drop that occurs with an ordinary semiconductor ...
