DUAL J-FET INPUT OPERATIONAL AMPLIFIER
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
These devices are low cost, high speed, dual JFET input
operational amplifiers with an internally trimmed input offset voltage.
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.
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
