Specification is for the device in free air:

14-lead plastic package: θJA = 150°C/W.

16-lead SOIC package: θJA = 100°C/W.

20-terminal LCC package: θJA = 150°C/W.

The input pins of this amplifier are protected by back-to-back diodes. If the

differential voltage exceeds ±0.7 volts, external series protection resistors

should be added to limit the input current to less than 25 mA.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

NOTES

1. ALL FOUR AMPLIFIERS ARE CONNECTED AS SHOWN.

1THE SIGNAL INPUT (SUCH THAT THE AMPLIFIER’S OUTPUT IS AT MAXIMUM

AMPLITUDE WITHOUT CLIPPING OR SLEW LIMITING) IS APPLIED TO ONE

AMPLIFIER AT A TIME. THE OUTPUTS OF THE OTHER THREE AMPLIFIERS ARE

THEN MEASURED FOR CROSSTALK.
