描述These devices are low cost, high speed, JFET input operational amplifiers with very lowinput offset voltage and input offset voltage drift. They require low supply current yet maintain alarge gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET inputdevices provide very low input bias and offset currents. The LF412-N-MIL dual is pin compatiblewith the LM1558, allowing designers to immediately upgrade the overall performance of existingdesigns.These amplifiers may be used in applications such as high speed integrators, fast D/Aconverters, sample and hold circuits and many other circuits requiring low input offset voltage anddrift, low input bias current, high input impedance, high slew rate and wide bandwidth.特性Internally Trimmed Offset Voltage: 1 mV(Max)Input Offset Voltage Drift: 7 μV/°C(Typ)Low Input Bias Current: 50 pALow Input NoiseCurrent: 0.01 pA / √HzWide Gain Bandwidth: 3 MHz(Min)High Slew Rate: 10V/μs (Min)Low Supply Current: 1.8mA/AmplifierHigh Input Impedance: 1012ΩLow Total Harmonic Distortion: ≤ 0.02%Low 1/f NoiseCorner: 50 HzFast Settling Time to 0.01%: 2 μsAll trademarks are the property of their respective owners.
