Features Internally trimmed offset voltage: 10 mV Low input bias current: 50pA Low input noise voltage: 25 nV/SqrtHz Low input noise current: 0.01 pA/SqrtHz Wide gain bandwidth: 4 MHz High slew rate: 13 V/µs Low supply current: 3.6 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, dual JFET input operational amplifiers with an internally trimmed input offset voltage (BI-FET II™ technology). 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 LF353 is pin compatible with the standard LM1558 allowing designers to immediately upgrade the overall performance of existing LM1558 and LM358 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, low input bias current, high input impedance, high slew rate and wide bandwidth. The devices also exhibit low noise and offset voltage drift.

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.
