A typical piezoelectric sensor comprises a disk of PZT-5A ceramic material with metallized electrodes on its surfaces. Applying electrically conductive epoxy to the electrodes connects external wiring ...

Since the dawn of time—or at least since the dawn of precision electronics—a major headache for analog designers has been CMV (common-mode-voltage)-induced errors, also known as the dreaded ground ...

Marantz announced their first headphone amplifier featuring integrated DAC, the retro-styled wooden HD-DAC1 for $799. This ultra-high quality component uses amplification technologies from Marantz’s ...

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.

We have had the good fortune of testing some of the industry's best multi-channel amplifiers. If you are from the camp that all amps sound the same, then don't waste your time reading another ...
