ULTRA-LOW-POWER DUAL OPERATIONAL AMPLIFIERS
FEATURES
• Low Supply Current . . . 85 µ A Typ
• Low Offset Voltage . . . 2 mV Typ
• Low Input Bias Current . . . 2 nA Typ
• Input Common Mode to GND
• Wide Supply Voltage . . . 3 V < V
• Pin Compatible With LM358
APPLICATIONS
• LCD Displays
• Portable Instrumentation
• Sensor/Metering Equipment
• Consumer Electronics (MP3 Players, Toys)
• Power Supplies
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
