TL/H/5649 LF353 Wide Bandwidth Dual JFET Input Operational Amplifier February 1995 LF353 Wide Bandwidth Dual JFET Input Operational Amplifier General Description These devices are low cost, high speed, dual JFET input operational amplifiers with an internally trimmed input offset voltage (BI-FET II TM 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. Features Y Internally trimmed offset voltage 10 mV Y Low input bias current 50pA Y Low input noise voltage 25 nV/ 0 Hz Y Low input noise current 0.01 pA/ 0 Hz Y Wide gain bandwidth 4 MHz Y High slew rate 13 V/ m s Y Low supply current 3.6 mA Y High input impedance 10 12 X Y Low total harmonic distortion A V e 10, k 0.02% RL e 10k, V O e 20Vp b p, BW e 20 Hz-20 kHz Y Low 1/f noise corner 50 Hz Y Fast settling time to 0.01% 2 m s Typical Connection Simplified Schematic 1/2 Dual Connection Diagrams Metal Can Package (Top View) Order Number LF353H See NS Package Number H08A Dual-In-Line Package (Top View) Order Number LF353M or LF353N See NS Package Number M08A or N08E TL/H/5649–1 BI-FET II TM is a trademark of National Semiconductor Corporation.
