3.4 Output configuration options
With the two-terminal differential output, two outputs configurations are possible to drive a piezo.
3.4.1 Differential output configuration
The typical output configuration is the differential output, refer to the figure below. The piezo element is driven
with one terminal connected to "HV+" and the other connected to "HV-". This configuration can achieve a
differential output voltage of 190 V
pp
in full-scale mode. Please limit the range to 60 V for TDK PowerHap
actuators with the DIP switches.
Figure 3: Two-terminal differential output configuration.
3.4.2 Single ended output configuration
The single ended output configuration allows to drive up to two different piezo elements, see Figure 4. A piezo
element is driven with one terminal connected to "HV+" or "HV-" and the other connected to "VDD". This
configuration can achieve a single ended output voltage of 95 V. Please limit the range to 60 V for TDK
PowerHap actuators with the DIP switches.
Only one piezo element can be driven at a time based on signal polarity.
