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.
INPUT SIGNAL
NOTES
1. ALL FOUR AMPLIFIERS ARE CONNECTED AS SHOWN.

THE SIGNAL INPUT (SUCH THAT THE AMPLIFIER’S OUTPUT IS AT MAXIMUM
Specification is for the device in free air:
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.
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.
