NJU7029

Low Noise C-MOS Single Operational Amplifier with Output Full-Swing

Japan Radio Corporation  

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 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.
