Key Features

  • Rail-to-rail output swing, allowing the output voltage to swing close to the supply rails.
  • Low supply current, with a typical value of 410 μA for all four amplifiers at 25°C.
  • No crossover distortion, ensuring clean and accurate signal amplification.
  • High unity-gain bandwidth of 1 MHz and a slew rate of 1 V/μs, suitable for high-frequency applications.
  • ESD protection exceeding JESD 22 standards, providing robust protection against electrostatic discharge.
  • Shutdown feature (for LMV324S), allowing the device to be powered down to reduce current consumption.
  • Common-mode input voltage range that includes ground, making it versatile for various input signal configurations.

Applications

  • Desktop PCs and netbooks.
  • HVAC (heating, ventilating, and air conditioning) systems.
  • Motor control, including AC induction motors.
  • Portable media players and professional audio mixers.
  • Telecom DC/DC modules and power supplies.
  • High-end and low-end washing machines and refrigerators.
