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™ 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 n Internally trimmed offset voltage: 10 mV n Low input bias current: 50pA n Low input noise voltage: 25 nV/ Hz n Low input noise current: 0.01 pA/ Hz n Wide gain bandwidth: 4 MHz n High slew rate: 13 V/μs n Low supply current: 3.6 mA n High input impedance: 10 12 n Low total harmonic distortion : 0.02% n Low 1/f noise corner: 50 Hz n Fast settling time to 0.01%: 2 μs Typical Connection 00564914 Simplified Schematic 1/2 Dual 00564916 Connection Diagram Dual-In-Line Package 00564917 Top View Order Number LF353M, LF353MX or LF353N See NS Package Number M08A or N08E BI-FET II™ is a trademark of National Semiconductor Corporation.

ESD Tolerance (Note 8) 1000V θ JA M Package TBD Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. Elec² trical Characteristics state DC and AC electrical specifications under particu² lar test conditions which guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guar² anteed for parameters where no limit is given, however, the typical value is a good indication of device performance.
