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.

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 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 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 V_OUT 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
