■ PACKAGE OUTLINE
NJM8502R
(MSOP8(VSP8))
■ GENERAL DESCRIPTION
The NJM8502 is a dual high precision JFET input operational amplifier featuring low offset, low offset drift,
low bias current, high slew rate, low noise and wide operating temperature range.
The precision performance, high speed and low noise make the NJM8502 especially suitable for filter
and amplification of high speed and small signal in instruments, automated test equipment, sensors and
other precision applications.
