7.2.3 Single-Supply Piezoelectric Driver

Some piezoelectric transducers can be referenced to ground as shown in Figure 7-4. The wide supply voltage of the OPAx596 enables designers to drive a high voltage transducer up to 85V, without having to use the more complicated bridge tied load configuration. The piezoelectric load presents a large capacitance at the output of the amplifier and proper compensation is required to avoid instability. Also consider the output current drive requirement. The current drive requirement is determined by the frequency of operation and the effective capacitance of the load. High frequency and large capacitance reduce the effective impedance of the load and thereby increase the current drive requirement. The OPAx596 are an excellent choice to drive piezoelectric loads at dc and low frequency.
