The two amplifiers share a common bias network and power
supply leads. Otherwise, their operation is completely inde-
pendent.
Features
nNo frequency compensation required
nShort-circuit protection
nWide common-mode and differential voltage ranges
nLow-power consumption
n8-lead can and 8-lead mini DIP
nNo latch up when input common mode range is
exceeded

Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package junction
to ambient thermal resistance), and TA(ambient temperature). The maximum allowable power dissipation at any temperature is PDmax =(T
Jmax -T
A)/θJA or the
number given in the Absolute Maximum Ratings, whichever is lower.
Note 3: For supply Voltages less than ±15V, the absolute maximum input Voltage is equal to the supply Voltage.
Note 4: Human body model, 1.5 KΩin series with 100 pF.
Note 5: Guaranteed by the CMRR test.
Note 6: Guaranteed parameter not tested.
