■PIN CONFIGURATION
The NJU7046 is a single rail to rail input/output
operational amplifier featuring high speed, low input bias
current and wide temperature range.
High-speed characteristics of slew rate(SR=9V/us) and
bandwidth (GBW=5MHz), low input bias current (IB=1pA
typ.) and wide temperature range(Ta=−40℃ to 125℃)
makes NJU7046 especially suitable for sensors and
filters application for industrial, buffers of input and output
for ADC, DAC, ASIC and other wide output swing
devices.
In addition to the NJU7046F3 is available in the
ultra-small SC88A package. This package saves space
on print circuit boards and enables the design of
Battery-powered instruments.
