Compensated
3 Description
The LM124-N series consists of four independent,
high-gain, internally frequency compensated
operational amplifiers designed 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 LM124-N
series can directly operate off of the standard 5-V
power supply voltage which is used in digital systems
and easily provides the required interface electronics
without requiring the additional ±15 V power supplies.
