Soft dB Mk3-HV1 Smart Piezo Drive Spec sheet User Manual
Page 2
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 amplifi er is automatically saved in the fl ash memory of the DSP board, so that it persists when
the amplifi er 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 DRIFT
The 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 for
high-speed Scanning Probe Microscopy applications.
INTERNAL POWER SUPPLY
The amplifi er uses an internal, very low-ripple, high-voltage power supply. This approach makes a compact one-box
solution with better control over the amplifi er’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 high
power transients.
VERSATILE AND SYMMETRICAL TOPOLOGY FOR EACH CHANNEL
The next fi gure presents the topology of the amplifi er for one channel. The X, Y and Z channels have the same topology:
