Low Noise, Rail-to-Rail Output Dual CMOS Operational Amplifier
■ GENERAL DESCRIPTION ■ PACKAGE OUTLINE
The NJU7029 is a CMOS operational amplifier that feature low
noise as VNI=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.
