FEATURES
1
•2 Internally Frequency Compensated for Unity
Gain
• Large DC Voltage Gain 100 dB
• Wide Bandwidth (Unity Gain) 1 MHz
(Temperature Compensated)
• Wide Power Supply Range:
– Single Supply 3V to 32V
– or Dual Supplies ±1.5V to ±16V
• Very Low Supply Current Drain (700
μA)—Essentially Independent of Supply
Voltage
• Low Input Biasing Current 45 nA (Temperature
Compensated)
• Low Input Offset Voltage 2 mV
– and Offset Current: 5 nA
• Input Common-Mode Voltage Range Includes
Ground
• Differential Input Voltage Range Equal to the
Power Supply Voltage
• Large Output Voltage Swing 0V to V⁺ − 1.5V
UNIQUE CHARACTERISTICS
• 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
• The Unity Gain Cross Frequency is
Temperature Compensated
• The Input Bias Current is also Temperature
Compensated
ADVANTAGES
• Eliminates Need for Dual Supplies
• Four Internally Compensated Op Amps in a
Single Package
• Allows Directly Sensing Near GND and V_OUT
also Goes to GND
• Compatible with All Forms of Logic
• Power Drain Suitable for Battery Operation
DESCRIPTION
The LM124-N 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
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 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.
