LM158/LM258/LM358/LM2904 Low Power Dual Operational Amplifiers January 2000 LM158/LM258/LM358/LM2904 Low Power Dual Operational Amplifiers General Description The LM158 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 series can be directly operated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ± 15V power supplies. The LM358 is also available in a chip sized package (8-Bump micro SMD) using National’s micro SMD package technology. Advantages n Two internally compensated op amps n Eliminates need for dual supplies n Allows direct sensing near GND and VOUT also goes to GND n Compatible with all forms of logic n Power drain suitable for battery operation n Pin-out same as LM1558/LM1458 dual op amp Features n Available in 8-Bump micro SMD chip sized package, (See AN-1112) n Internally frequency compensated for unity gain n Large dc voltage gain: 100 dB ...
