DESCRIPTION/ORDERING INFORMATION

The LP358 and LP2904 are dual 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 LP358 and LP2904 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 V (3) Differential voltages are at IN+, with respect to IN–. (4) Short circuits from outputs to V (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 TJof 150 ° C can affect reliability. (6) The package thermal impedance is calculated in accordance with JESD 51-7.
