The VF-90 is compatible with National Instruments's CompactRio and CompactDaq modular chassis, thus enabling the use of the amplifier in both open- and closed-loop motion control applications
DSM has introduced the ultra-compact VF-90 linear piezoelectric amplifier for space-constrained and OEM applications The product is a new addition to DSM's line of voltage follower linear amplifiers and offers several performance features ideal for driving piezoelectric loads in actuators and stages

Stress testing at the nano scale
Material stress testing tool incorporates a flexure-based piezoelectric positioner, a capacitive probe displacement sensor, and a high-resolution load cell for testing of thin films under stress
Key product specifications include a maximum and peak current output of 90mA and three factory-configured output voltage ranges (-30/150V, -30/200V, +/-100V).
The product's bandwidth is greater than 5kHz (-3dB), and electrical noise on the output is approximately 2mV,rms.
Circuit protection includes over-current, over-temperature, and short-circuit protection.
The VF-90 has also achieved FCC and CE certifications for product safety and emissions/immunity.
The VF-90 is ideal as a single channel amplifier for use in open-loop, lower-power applications driving piezoelectric motion devices.
Typical applications include optical fibre stretching, optical scanning, metrology, and proportional valve control.
