NJU7029
Low Noise, Rail-to-Rail Output Dual CMOS Operational Amplifier
■
GENERAL DESCRIPTION
The NJU7029 is a CMOS operational amplifier that feature
low noise as V
NI
=13V/√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.
