Description
GeneralDescriptio
The LM158 series consists of two independent, high gain,internally frequency compensated operational amplifierswhich were designed specifically to operate from a singlepower supply over a wide range of voltages. Operation fromsplit power supplies is also possible and the low powersupply current drain is independent of the magnitude of thepower supply voltage.Application areas include transducer amplifiers, dc gainblocks and all the conventional op amp circuits which nowcan be more easily implemented in single power supplysystems. For example, the LM158 series can be directlyoperated off of the standard +5V power supply voltage whichis used in digital systems and will easily provide the requiredinterface electronics without requiring the additional±15Vpower supplies.The LM358 and LM2904 are available in a chip sized pack-age (8-Bump micro SMD) using National’s micro SMD pack-age
