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