The LP324 and LP2902 are quadruple low-power operational amplifiers especially designed for battery-operated applications. Good input specifications and a wide supply-voltage range are achieved, despite the ultra-low supply current. Single-supply operation is achieved with an input common-mode range that includes ground (GND).

The LP324 and LP2902 are an excellent choice for 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, and so forth), and power supplies.
