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 comput-

er control. In such complex systems the PA93/27 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.
