REV. A
Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and 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.
Specification is for device in free air:
14-Pin Plastic Package:
14-Pin Cerdip Package:
16-Pin SOIC Package:
20-Terminal LCC Package:
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.

All min and max specifications are guaranteed.
Specifications subject to change without notice.
Bias current specifications are guaranteed maximum at either input.
Input bias current match is the maximum difference between corresponding inputs of all four amplifiers.
CMRR match is the difference of V
PSRR match is the difference between V
See Figure 2a for test circuit.

THE SIGNAL INPUT (SUCH THAT THE AMPLIFIER'S OUTPUT IS AT MAX
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.
ALL 4 AMPLIFIERS ARE CONNECTED AS SHOWN
