The LP358 and LP2904 devices 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 devices are ideal in applications where wide supply voltages and low power are more important than speed and bandwidth. These applications include portable instrumentation, LCD displays, consumer electronics (MP3 players, toys, and so forth), and power supplies.
