Voltage Monitor
The QPA3202 offers an auxiliary analog output for feedback control or 
monitoring  the  differential  output  voltage.   The  monitor  output  is  a 
replica  of  the  load  voltage  scaled  by  a  factor  of  1/50  (0.02  V/V).   This 
output  should  be  connected  only  to  an  oscilloscope  or  other  high‐
impedance monitoring device. 
Output Current Limit
Piezoelectric  actuators  can  be  effectively  modeled  by  a  simple 
capacitor.   There  is  significant  resistance  in  series  with  the  capacitor, 
but this is neglected here.  Like any other amplifier, the drive frequency 
limitation  of  the  QPA3202  is  a  function  of  its  peak  current  capability, 
according to the familiar equation:

Since the current limit of the QPA3202 is 2 Amperes (2A), the 
maximum output voltage slew rate is 2/C where C is the piezo 
capacitance.  For a pure sinusoid with frequency f (in Hz) and 
amplitude Vo (zero to peak), the maximum rate or derivative is 
o
V
f

.  Therefore, the maximum drive frequency as a function of 
output amplitude Vo and load capacitance C can be expressed by: 
C
V
f
o

The  maximum  frequency  fmax  is  the  frequency  at  which  the  output 
waveform  becomes  distorted  by  current‐limiting.   Sinusoids,  for 
example, will become linear at zero crossings.   Operation is permitted 
beyond  this  frequency  provided  that  internal  temperature  limitations 
are not exceeded (see following sections).  Large capacitive loads may 
also de‐stabilize the amplifier.  Note that this constraint is in addition 
to the amplifier bandwidth, which is limited to 8kHz. 
Thermal Overload Protection
High internal power dissipation is common to all linear amplifiers that 
are designed to drive capacitive loads.  This dissipation is a function of 
load  capacitance,  output  voltage  amplitude,  and  drive  frequency.   In 
general, increasing any of these variables increases power dissipation.  
If  there  are  no  means  to  limit  this  effect,  heavy  loads  will  cause 
excessive  temperatures  that  can  overheat  and  damage  the  amplifier.  
For  this  reason  the  QPA3202  is  equipped  with  internal  temperature 
monitoring  circuitry.   When  the  internal  temperature  exceeds  a 
predefined  threshold,  the  QPA3202  will  enter  thermal  shutdown  mode.  
In  this  mode  the  amplifier  is  automatically  switched  off  and  the  OT 
LED  indicator  is  illuminated.   The  instrument  will  remain  in  this 
condition until the user recycles the power supply and the temperature 
has decreased to a safe level.   
 
Figure  3  indicates  the  thermal  shutdown  boundary  as  a  function  of 
frequency  and  load  capacitance  for  full‐scale  output  (200V  sinusoid).  
This  curve  applies  to  steady‐state  operation  only.   The  QPA3202  is 
capable  of  operating  beyond  this  curve  provided  that  the  duration  of 
operation (or duty‐cycle) is low enough to prevent over‐heating.
