Low-Power Quad-Operational Amplifier (LM324N)

The LM324N consists of four independent, high-gain, internally frequency compensated operational amplifiers designed to operate from asingle 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.

Features:

• 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

Applications:

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