 Description
The LM324/LM324A,LM2902,LM224/LM224A consist of four independent, high gain, internally frequency compensated operational amplifiers which were designed
specifically to operate from a single power supply over a wide voltage range. operation from split power supplies is also possible so long as the difference between the two supplies is 3 volts to 32 volts. Application areas include transducer amplifier, DC gain blocks and all the conventional OP Amp circuits which now can be easily implemented in single power supply systems.

max232cpe (+5V-Powered, Multichannel RS-232 Drivers/Receivers)

General Description
The MAX220–MAX249 family of line drivers/receivers is
intended for all EIA/TIA-232E and V.28/V.24 communications
interfaces, particularly applications where ±12V is
not available.
These parts are especially useful in battery-powered systems,
since their low-power shutdown mode reduces
power dissipation to less than 5μW. The MAX225,
MAX233, MAX235, and MAX245/MAX246/MAX247 use
no external components and are recommended for applications
where printed circuit board space is critical.
