Description
DSM's VF-90 linear piezoelectric amplifier module provides functionality for driving piezoelectric (capacitive) loads in a compact form factor. Provides 90 mA maximum continuous and peak current for piezo devices rated for up to 150 V. Low noise for precision applications; 0.5 mVrms typical. The VF-90 features over-current, over-temperature, and short-circuit protection as well as protection against over/under voltage conditions on the power line.
