概要

The LFx5x devices are the first monolithic JFET input operational amplifiers to incorporate well-matched, high-voltage JFETs on the same chip with standard bipolar transistors (BI-FET™ Technology). These amplifiers feature low input bias and offset currents/low offset voltage and offset voltage drift, coupled with offset adjust, which does not degrade drift or common-mode rejection. The devices are also designed for high slew rate, wide bandwidth, extremely fast settling time, low voltage and current noise and a low 1/f noise corner.

特長

  • Advantages
    • Replace Expensive Hybrid and Module FET
      Op Amps
    • Rugged JFETs Allow Blow-Out Free Handling
      Compared With MOSFET Input Devices
    • Excellent for Low Noise Applications Using
      Either High or Low Source Impedance–Very
