The AD628 common-mode differential amplifier is said to be the first such device to provide programmable gain. Using an external resistor, the amplifier can be set for a gain range from 0.1 to 1,000.
The popular FDA comes in both Current Feedback Amplifier (CFA) and Voltage Feedback Amplifier (VFA) variants. The CFA versions tend to be used in AC-coupled applications where their great full power ...
Some of the electrical signals we work with are said to be “floating” with respect to ground. A typical example might be a voltage drop over a shunt resistor in a power supply or a complex biomedical ...
