LF412-N - Low Drift Dual JFET Input Operational Amplifier

Description

These devices are low cost, high speed, JFET input operational amplifiers with very low input offset voltage and input offset voltage drift.

They require low supply current yet maintain a large gain bandwidth product and fast slew rate.

Features

  • 1 Internally Trimmed Offset Voltage: 1 mV (Max).
  • Input Offset Voltage Drift: 7 µV/°C (Typ).
  • Low Input Bias Current: 50 pA.
  • Low Input Noise Current: 0.01 pA / √Hz.
  • Wide Gain Bandwidth: 3 MHz (Min).
  • High Slew Rate: 10V/µs (Min).
  • Low Supply Current: 1.8 mA/Amplifier.
  • High Input Impedance: 1012Ω.
  • Low Total Harmonic Distortion: ≤0.02%.
  • Low 1/f Noise Corner: 50 Hz.
  • Fast Settling Time to 0.01%: 2 µs 2 App.
