NOTES: 1. Unless otherwise noted: TC = 25°C, DC input specifications are ± value given. Power supply voltage
is typical rating. RC = 100 CC = 220pF.
2. Long term operation at the maximum junction temperature will result in reduced product life. Derate
internal power dissipation to achieve high MTTF.
3. +VS and –VS denote the positive and negative power supply rail respectively.
4. Rating applies if the output current alternates between both output transistors at a rate faster than
60Hz.
5. Derate max supply rating .625 V/°C below 25°C case. No derating needed above 25°C case.
TYPICAL APPLICATION
LOW POWER, PIEZOELECTRIC POSITIONING
Piezo positioning may be applied to the focusing of segmented
mirror systems. The composite mirror may be composed of
hundreds of elements, each requiring focusing under computer
control. In such complex systems the PA93 reduces the costs
of power supplies and cooling with its advantages of low cost
and low quiescent power consumption while increasing circuit
density with the SIP package.
