Precision, Low Noise, Rail-to-Rail Output,
CMOS Operational Amplifier
■ GENERAL DESCRIPTION
The NJU7076/NJU7077/NJU7078 is
■ PACKAGE OUTLINE
a
high precision
Rail-to-Rail output Single/Dual/Quad 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..
NJU7076F
(SOT-23-5)
NJU7077R
(MSOP8(VSP8))
The output swing can reach 20 mV from the rails, while driving
a 10kΩ load (at 5V operation). The NJU7076/NJU7077/
NJU7078 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/NJU7078 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-.
(2) 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.
