Features Internally trimmed offset voltage: 0.5 mV(max) Input offset voltage drift: 10 µV/°C(max) Low input bias current: 50 pA Low input noise current: 0.01 pA/SqrtHz Wide gain bandwidth: 3 MHz(min) High slew rate: 10V/µs(min) Low supply current: 1.8 mA High input impedance: 1012 Low total harmonic distortion: <=0.02% Low 1/f noise corner: 50 Hz Fast settling time to 0.01%: 2 µs Description These devices are low cost, high speed, JFET input operational amplifiers with very low input offset voltage and guaranteed input offset voltage drift. They require low supply current yet maintain a large gain bandwidth product and fast slew rate. In addition, well matched high voltage JFET input devices provide very low input bias and offset currents. The LF411 is pin compatible with the standard LM741 allowing designers to immediately upgrade the overall performance of existing designs. These amplifiers may be used in applications such as high speed integrators, fast D/A converters, sample and hold circuits and many other circuits requiring low input offset voltage and drift, low input bias current, high input impedance, high slew rate and wide bandwidth.

LF411ACN	BIFET	0	12875	0	0	1065000	4	302196657
LF411CN	BIFET	0	12875	0	0	1065000	4	302196657

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
