Smart Piezo Drive Model Mk3-HV1
Programmable & Self-instrumented 200 Volt Amplifier

The Smart Piezo Drive is a 6-channel, very low-noise, low-drift, high-voltage amplifier for Scanning-Probe Microscopy
applications. With three main inputs, three auxiliary inputs, a wide range of possible adjustments of the parameters(output offsets, gains and bandwidths), the Smart Piezo Drive is a feature-rich, extremely versatile product.

INDUSTRY FIRSTS• Embedded high-precision DSP board allows the amplifier to be completely software-controlled through a USB or Ethernet link
• 3-channel real-time scope with unlimited recording function• Low-pass filtering and adjustable slew-rate limit on offset changes to avoid crashes due to fast motions• Emergency Return-to-Preset function immediately returns all outputs to a preset “safe” position, with a slew-rate limit
during the return• Drift-Correction function to track thermal drifts of the scanned surface• Completely software-controllable parameters on all channels:
ü Bandwidth (1kHz to 50kHz)
ü Gain (x1 to x20)
ü Offset (full range)

SOFTWARE CONTROL INTERFACEThis interface, based on a DSP board, uses a USB or an Ethernet link to control the amplifier.
The following interface allows the full control of the amplifier.

The user can monitor the output voltage history on all channels and adjust the gain, the offset and the bandwidth.
The entire set-up of the amplifier is automatically saved in the flash memory of the DSP board, so that it persists when
the amplifier is powered off.
The USB version of the interface provides a high sampling rate scope function to monitor, in real-time, the output signal
on all outputs, with an adjustable history length up to 60s.

FAST OPERATION WITH LOW NOISE AND DRIFTThe noise level is below 120 µVrms for a gain of 20 (input shorted and a bandwidth of 50 kHz). The low noise
and thermal stability combined with the very high bandwidth (50 kHz) make the Smart Piezo Drive the best choice forhigh-speed Scanning Probe Microscopy applications.

INTERNAL POWER SUPPLYThe amplifier uses an internal, very low-ripple, high-voltage power supply. This approach makes a compact one-box
solution with better control over the amplifier’s performance.

THERMAL MANAGEMENT
The fanless thermal management uses an alumimum plate that weights about 1 kg, and the aluminum enclosure itself
acts as a thermal mass and radiator for a greater thermal stability. This mass can absorb the heat generated by highpower transients.

VERSATILE AND SYMMETRICAL TOPOLOGY FOR EACH CHANNEL
The next figure presents the topology of the amplifier for one channel. The X, Y and Z channels have the same topology:
