MSOP8 (VSP8)*
The NJU7076/NJU7077/NJU7078 are single/dual/Quad
channel, precision, low-noise, rail-to-rail output CMOS
operational amplifiers. These devices featuring a low input
offset voltage (50µV max.), low temperature drift (0.5µV/°C
typ.), and low bias current (1pA typ.). The combination of
these specifications makes the devices well-suited for sensor
applications such as temperature sensors, weight sensors,
high-precision current sensing amplifiers, and current-voltage
converters.
The output swing can reach 20 mV from the rails while driving
a 10kΩ load (at 5V operation). Input voltage includes ground,
enabling direct sensing near ground.
The NJU7076/NJU7077/NJU7078 have high EMI immunity
to reduce malfunctions, making them ideal for EMI-sensitive
applications.

Differential voltage is the voltage difference between +INPUT and -INPUT.
For supply voltage less than 7V, the absolute maximum rating is equal to the supply voltage.
The absolute maximum input voltage is limited at 7V.

NJU7076/NJU7077/NJU7078
Common-Mode Input Voltage Range
When the supply voltage does not meet the condition of
electrical characteristics, the range of common-mode
input voltage is as follows:
VICM (typ.) = V− to V+-1 (Ta = 25°C)
Difference of VICM when Temperature change, refer to
typical characteristic graph.
During designing, consider variations in characteristics
for use with allowance.
Maximum Output Voltage Range
When the supply voltage does not meet the condition
of electrical characteristics, the range of the typ. value
of the maximum output voltage is as follows:
VOM (typ.) = V-+20mV to V+-20mV (RL=10kΩ to V+/2, Ta=25°C)
During designing, consider variations in characteristics
and temperature characteristics for use with allowance.
In addition, also note that the output voltage range
becomes narrow as shown in typical characteristics
graph when an output current increases.
Capacitive Load
The NJU7076/NJU7077/NJU7078 can use at unity
gain follower, but the unity gain follower is the most
sensitive configuration to capacitive loading. The
combination of capacitive load placed directly on the
output of an amplifier along with the output impedance
of the amplifier creates a phase lag which in turn
reduces the phase margin of the amplifier. If phase
margin is significantly reduced, the response will cause
overshoot and ringing in the step response.
The NJU7076/NJU7077/NJU7078 are unity gain stable
for capacitive loads of 470pF. To drive heavier
capacitive loads, an isolation resistor, RISO as shown
Figure1, should be used. RISO improves the feedback
loop’s phase margin by making the output load
resistive at higher frequencies. The larger the value of
RISO, the more stable the output voltage will be.
However, larger values of RISO result in reduced output
swing, reduced output current drive and reduced
frequency bandwidth.
EMIRR (EMI Rejection Ratio) Definition
EMIRR is a parameter indicating the EMI robustness of
an Op-Amp. The definition of EMIRR is given by the
following equation1.
EMIRR = 20 ∙ log ൬
Vୖ_
൰
|∆V୍ |
− eq. 1
−−
Vୖ_ : RF Signal Amplitude [VP]
∆V୍ : Input offset voltage shift quantity [V]
The tolerance of the RF signal can be grasped by
measuring an RF signal and offset voltage shift
quantity. Offset voltage shift is small so that a value of
EMIRR is big. And it understands that the tolerance for
the RF signal is high. In addition, about the input offset
voltage shift with the RF signal, there is the thinking
that influence applied to the input terminal is dominant.
Therefore, generally the EMIRR becomes value that
applied an RF signal to +INPUT terminal.

■ APPLICATION NOTE
Single and Dual Supply Voltage Operation
The NJU7076/NJU7077/NJU7078 work with both
single supply and dual supply when the voltage
supplied is between V+ and V−. These amplifiers
operate from single 2.2 to 5.5V supply and dual ±1.1V
to ±2.75V supply.
