Norwood, Mass. – Goaded by its own analog-to-digital converter engineers, who bemoaned the industry-wide performance disparity between high-performance A/Ds and the amplifiers available to drive them, ...

Although current-feedback operational amplifiers (op amps) have been on the market since the 1990s, the current-feedback fully differential amplifier was not introduced until 2007. There are several ...

Fully differential amplifiers have grown in popularity because of their low distortion, excellent noise rejection, and the simplicity of interfacing them with differential analog-to-digital converters ...

Each fully differential amp channel is actually two separate channels, each driving either the positive or negative signals, with the signal bridged at the output as seen in the block diagram above.

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.
