1 Features
1
• 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 3 V to 32 V
– or Dual Supplies ±1.5 V to ±16 V
• Very Low Supply Current Drain (700 A)μ
—Essentially Independent of Supply Voltage
• Low Input Biasing Current 45 nA
(Temperature Compensated)
• Low Input Oset Voltage 2 mV
and Oset Current: 5 nA
• Input Common-Mode Voltage Range Includes
Ground
• Dierential Input Voltage Range Equal to the
Power Supply Voltage
• Large Output Voltage Swing 0 V to V +−1.5 V
•Advantages:
– Eliminates Need for Dual Supplies
– Four Internally Compensated Op Amps in a
Single Package
– Allows Direct Sensing Near GND and VOUT
also Goes to GND
– Compatible With All Forms of Logic
– Power Drain Suitable for Battery Operation
– In the Linear Mode the Input Common-Mode,
Voltage Range Includes Ground and the
Output Voltage
– Can Swing to Ground, Even Though Operated
from Only a Single Power Supply Voltage
– Unity Gain Cross Frequency is Temperature
Compensated
– Input Bias Current is Also Temperature
Compensated
2 Applications
• Transducer Ampliers
• DC Gain Blocks
• Conventional Op Amp Circuits
3 Description
The LM124-N series consists of four independent,
high-gain, internally frequency compensated
operational ampliers 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 ampliers, 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 o 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.
