詳細說明

The LF444CM/NOPB stands out as a quad low power operational amplifier that offers superior DC performance compared to the LM148. Despite sharing the same AC characteristics as the LM148 in terms of bandwidth, slew rate, and gain, this amplifier consumes only a quarter of the supply current, resulting in significant energy savings. Its well-matched high voltage JFET input devices significantly reduce input bias and offset currents by a factor of 10,000 compared to the LM148, ensuring improved accuracy in signal processing. With a low equivalent input noise voltage, the LF444CM/NOPB is an excellent choice for applications where low power dissipation and high-quality electrical characteristics are essential considerations

主要特徵

  • This amplifier has low input bias current for reduced thermal noise
  • It also offers low input capacitance for improved high-frequency performance
  • Suitable for audio, medical devices, and industrial equipment
