■ GENERAL DESCRIPTION

The NJU7009 is a CMOS operational amplifier that feature

low noise as 13nV/√Hz typ. @ f=1kHz, low operating voltage.

FET input devices provide very low input bias current and

suitable for applications uses current signal such as

accelerometers, shock sensors and photodiode amplifiers.
