New Japan Radio NJU7077
NJU7076/NJU7077
Precision, Low Noise, Rail-to-Rail Output,
CMOS Operational Amplifier
GENERAL DESCRIPTION
The NJU7076/NJU7077 is a high precision Rail-to-Rail output
Single/Dual CMOS operational amplifier featuring a low noise
of 10nV/Hz typ., low input offset voltage of 150µV max., low
temperature drift of 0.5µV/°C typ. and low bias current of 1pA
typ..
The output swing can reach 20 mV from the rails, while driving
a 10kΩ load (at 5V operation). The NJU7076/NJU7077 also
has a high RF noise immunity which can reduce malfunctions
caused by RF noises from mobile phones and others. The
combination of these specifications makes the NJU7076/
NJU7077 well-suited for sensor applications such as a
temperature sensor, weight sensor and others, high precision
current sensing amplifiers and current voltage converters.

(1) Supply Voltage is the voltage difference between V+ and V-.
(1) Differential voltage is the voltage difference between +INPUT and -INPUT.
(3) For supply voltage less than 7V, the absolute maximum rating is equal to the supply voltage.
(4) Power dissipation is the power that can be consumed by the IC at Ta=25°C, and is the typical measured value based on
JEDEC condition. When using the IC over Ta=25°C subtract the value [mW/°C]=PD/(Tstg(MAX)-25) per temperature.
