LM124/LM224/LM324/LM2902
Low Power Quad Operational Amplifiers
General Description
The LM124 series 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 sup-
ply 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 sys-
tems. For example, the LM124 series can be directly oper-
ated 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.
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 VOUT also goes
to GND
n Compatible with all forms of logic
n Power drain suitable for battery operation
Features
n Internally frequency compensated for unity gain
n Large DC voltage gain 100 dB
n Wide bandwidth (unity gain) 1 MHz
(temperature compensated)
n Wide power supply range:
Single supply 3V to 32V
or dual supplies ±1.5V to ±16V
n Very low supply current drain (700 µA) — essentially
independent of supply voltage
n Low input biasing current 45 nA
(temperature compensated)
n Low input offset voltage 2 mV
and offset current: 5 nA
n Input common-mode voltage range includes ground
n Differential input voltage range equal to the power
supply voltage
n Large output voltage swing 0V to V+ − 1.5V
