LF453 Wide-Bandwidth Dual JFET-Input Operational Amplifiers December 1994 LF453 Wide-Bandwidth Dual JFET-Input Operational Amplifiers General Description The LF453 is a low-cost high-speed dual JFET-input operational amplifier with an internally trimmed input offset voltage (BI-FET II technology) The device requires a low supply current and yet the amplifiers maintain a large gain bandwidth product and a fast slew rate In addition well matched high voltage JFET input devices provide very low input bias and offset currents The LF453 is pin compatible with the standard LM1558 allowing designers to upgrade the overall performance of existing designs The LF453 may be used in such applications as high-speed integrators fast D A converters sample-and-hold circuits and many other circuits requiring low input bias current high input impedance high slew rate and wide bandwidth Features Y Y Y Y Y Y Y Y Y Y Internally trimmed offset voltage Low input bias current Low input noise current Wide gain bandwidth High slew rate Low supply current High input impedance Low total harmonic distortion AV e 10 RL e 10k VO e 20 Vp– p f e 20 Hz – 20 kHz Low 1 f noise corner Fast settling time to 0 01% 5 0 mV (max) 50 pA (typ) 0 01 pA SHz (typ) 4 MHz (typ) 13 V ms (typ) 6 5 mA (max) 1012X (typ) k 0 02% (typ) 50 Hz (typ) 2 ms (typ) Typical Connection Connection Diagram SO Package TL H 9710 – 2 Top View Order Number LF453CM See NS Package Number M08A TL H 9710 – 1 Simplified Schematic TL H 9...
