Micropower Quad Operational Amplifier
LP324/LP2902 Micropower Quad Operational Amplifier
July 2001
General Description
The LP324 series consists of four independent, high gain
internally compensated micropower operational amplifiers.
These amplifiers are specially suited for operation in battery
systems while maintaining good input specifications, and
extremely low supply current drain. In addition, the LP324
has an input common mode range, and output source range
which includes ground, making it ideal in single supply applications.
These amplifiers are ideal in applications which include portable instrumentation, battery backup equipment, and other
circuits which require good DC performance and low supply
current.

Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.
Note 2: The input voltage is not allowed to go more than −0.3V below V
device.
Note 3: Short circuits from the output to GNDcan cause excessive heatingand eventual destruction.The maximum sourcing output current is approximately30 mA
independent of the magnitude of V
(particularly at elevated temperatures) and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.
Note 4: For operation at elevated temperatures, these devices must be derated based on a thermal resistance of θ
Note 5: The LP2902 may be operated from −40˚C ≤ T
Note 6: Boldface numbers apply at temperature extremes. All other numbers apply only at T
unless otherwise specified.
Note 7: Guaranteed and 100% production tested.
Note 8: Guaranteed (but not 100%production tested) over theoperating supply voltage range(3.0V to 32V forthe LP324, LP324, and 3.0V to 26V for the LP2902),
and the common mode range (0V to V
Note 9: The LP2902 operating supply range is 3V to 26V, and is not tested above 26V.
Note 10: The test circuit used consists of the human body model of 100 pF in series with 1500Ω.
