LM124A/LM124QML
Low Power Quad Operational Amplifiers
General Description
The LM124/124A consists of four 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 LM124/124A can be directly op-
erated off of the standard +5Vdc power supply voltage which
is used in digital systems and will easily provide the required
interface electronics without requiring the additional +15Vdc
power supplies.
Unique Characteristics
n
In the linear mode the input common-mode voltage
range includes ground and the output voltage can also
swing to ground, even though operated from only a
single power supply voltage
n
The unity gain cross frequency is temperature
compensated
n
The input bias current is also temperature compensated
Advantages
n
Eliminates need for dual supplies
n
Four internally compensated op amps in a single
package
n
Allows directly sensing near GND and V
OUT also goes
to GND
n
Compatible with all forms of logic
n
Power drain suitable for battery operation
