DESCRIPTION/ORDERING INFORMATION
The LP324 and LP2902 are quadruple low-power operational amplifiers especially suited for battery-operated
applications. Good input specifications and wide supply-voltage range still are achieved, despite the ultra-low
supply current. Single-supply operation is achieved with an input common-mode range that includes GND.
The LP324 and LP2902 are ideal in applications where wide supply voltage and low power are more important
than speed and bandwidth. These applications include portable instrumentation, LCD displays, consumer
electronics (MP3 players, toys, etc.), and power supplies.

(1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating
conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values (except differential voltages and VCC specified for the measurement of IOS) are with respect to the network GND.
(3) Differential voltages are at IN+, with respect to IN–.
(4) Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
(5) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
(6) The package thermal impedance is calculated in accordance with JESD 51-7.
