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 ...

The traditional three op-amp differential amplifier's signal to noise ratio can be improved by 6dB by adding a resistor and slightly changing the connections. There is a trade-off though: The ...

While traditional amplifiers use external resistors to set gain, a new amplifier family integrates on-board thin-film precision resistors that can be selected by pin ...
