Overview
The Piezo driver MTAD3001 is a linear amplifier with high precision and low noise,
designed to drive capacitive load such as the piezoelectric actuators. A DC bias can be
applied easily with knob attached. Therefore, a bias voltage can be easily added to the
intended driving pattern. A built-in protector is attached inside to detect malfunction such
as overload and short circuit. The built-in protector will activate when the average output
currents goes above 1 Amp or the peak output current goes above
±
5 Amp. The built-in
protector is also designed to adopt into customer control system. The malfunction can be
detected externally and the reset action can be done with external signal. A BNC connector
is attached for monitoring the output voltage by converting the output voltage to 1/10. With
the MTAD3001, the piezoelectric actuators can be driven at any intended driving
waveforms or with a closed loop control system.
