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 and LM2904 are available in a chip sized package
(8-Bump micro SMD) using National’s micro SMD package
technology.
