GM358
LOW POWER DUAL
OPERATIONAL AMPLIFERS
Description
The GM358 consists of two high gain, internally
frequency compensated operational amplifiers
which are designed to operated from a single
power supply over a wide range of voltages.
Operation from split power supplies is also
available. The GM358 feature low power drain, a
common mode input voltage range extending to
GND/VEE. The GM358 is equivalent to one-half
of the GM324.
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 GM358 can be directly operated 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 GM358 is available in SOP-8 and DIP-8
packages.
