SPECIFICATIONS

NOTES:

The specification for PA41A/PA42A is identical to the specification for PA41/PA42 in applicable column to the left.

Unless otherwise noted T

C = 25°C, CC = 18pF, RC = 2.2K. DC input specifications are ± value given. Power supply voltage is

typical rating.

Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation

to achieve high MTTF. For guidance, refer to heatsink data sheet.

Derate maximum supply voltage .5 V/

°C below case temperature of 25°C. No derating is needed above T

C = 25°C.

Sample tested by wafer to 95%.

Guaranteed but not tested.

The selected value of R

CL must be added to the values given for total output resistance.

Specifications separated by / indicate values for the PA41 and PA42 respectively.
