Act as Driver of Piezoelectric Element
Besides, PA1011 could also be used as the driver of piezoelectric
element (10W driver, with additional impedance transformer).
Particularly the piezoelectric element with higher electrostatic
capacity (up to 1000pF), better step responses are gainable from
the PA1011 because of its tiny output impedance.
