3 Description

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.
