Page 3: Introduction
1 Introduction The PD200 is a high bandwidth, low noise linear amplifier for driving piezoelectric actuators. The output voltage range can be unipolar, bipolar, or asymmetric from 50V to 200V. Up to +/-200V can be achieved in the bridged configuration. The PD200 can drive any load impedance including unlimited capacitive loads such as stack actuators;... -

Page 5: Output Voltage Range
Table 1. Voltage range configurations 5 Output Current The PD200 has a peak and average current limit as described in Table 1. The RMS current limit defines the maximum frequency that is achievable with a capacitive load. This topic is discussed in “Power Bandwidth”. -
Page 6: Pulse Current Option
For applications that require a high peak current, the peak current limit can be increased to 10 Amps by appending the order code with “-PULSE”, e.g. “PD200-V0,200-PULSE”. In this configuration, the average current limit remains the same; however, the peak current limit is increased to 8 Amps and the maximum pulse duration is reduced to the time listed in Table 2. -
Page 7: Power Bandwidth
The slew-rate is approximately 150 V/uS which implies a maximum frequency of 150 × 10 ������ �� ���� �� �� In the following figures, the maximum peak-to-peak voltage is plotted against frequency and capacitance.
