LM324N Datasheet

Quadruple Operational Amplifiers


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 ndependent of the magnitude of the power supply voltage.

• 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
• 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 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
   – Input Bias Current is Also Temperature

• Transducer Amplifiers
• DC Gain Blocks
• Conventional Op Amp Circuits
