LP324/LP2902 is a four-channel micropower operational amplifier produced by National Semiconductor Corporation. It has extremely low supply current, output power range and input common mode range, and is suitable for applications such as portable instrumentation, battery backup equipment, and other circuits that require good DC performance and low supply current.
The LP324 and LP2902 series consist of four independent, high gain, internally compensated micropower operational amplifiers. These devices are specifically designed for battery-powered systems, offering extremely low supply current drain while maintaining good input specifications. They are ideal for single supply applications due to an input common mode range and output source range that includes ground.
