NJU7058
The NJU7056/NJU7057/NJU7058 are Single/Dual/
Quad rail-to-rail output CMOS operational amplifiers.
Low noise of 15nV/√Hz and low offset drift of 0.7µV/°C
typ. make them suitable for several sensor amplifiers
and preamplifiers.
NJU7056/NJU7057/NJU7058 operate from 1.8V to
5.5V supply voltage. They are optimized for 2-cell battery
systems and 1-cell Li-ion battery systems. The
NJU7056/NJU7057/NJU7068 have high-impedance
inputs with ground sensing, rail-to-rail output that swings
within 50mV from rail with 10kΩ load at 1.8V supply,
2.1MHz gain bandwidth and 0.8V/µs Slew rate. These
characteristics make them excellent performance for
general-purpose applications.
The NJU7056 is available in 5-pin SC-88A and SOT23 packages. NJU7057 is offered in 8-pin MSOP
(TVSP): meet JEDEC MO-187-DA / thin type package
and DFN that is thin and 2mm square small package.
NJU7058 is offered in 14-pin SSOP package.

(1) The absolute maximum input voltage is limited at 7V.
(2) Input voltages outside the supply voltage will be clamped by ESD protection diodes. If the input voltage exceeds the supply voltage,
the input current must be limited 10 mA or less by using a restriction resistance.
(3) 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.

■ APPLICATION NOTE
Single and Dual Supply Voltage Operation
The NJU7056/NJU7057/NJU7058 works with both
single supply and dual supply when the voltage
supplied is between V+ and V−. These amplifiers
operate from single +1.8 to +5.5V supply and dual
±0.9V to ±2.75V supply.
Common-Mode Input Voltage Range
When the supply voltage does not meet the condition
of electrical characteristics, the range of commonmode input voltage is as follows:
−
+
VICM (typ.) = V to V -0.9 (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-+50mV to V+-50mV (RL=20kΩ 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.
Input Voltage Exceeding the Supply Voltage
Inputs of the NJU7056/NJU7057/NJU7058 are
protected by ESD diodes (shown in Figure1) that will
conduct if the input voltages exceed the power
supplies by more than approximately 300mV.
Momentary voltages greater than 300mV beyond the
power supply, inputs can be tolerated if the current is
limited to 10mA. Figure2 is easily accomplished with
an input resistor. If the input voltage exceeds the
supply voltage, the input current must be limited
10mA or less by using a restriction resistance (RLIMIT)
as shown in figure2.

exceeding the Supply Voltage.
Capacitive Load
The NJU7056/NJU7057/NJU7058 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 NJU7056/NJU7057/NJU7058 is unity gain stable
for capacitive loads of 200pF. To drive heavier
capacitive loads, an isolation resistor, RISO as shown
Figure3, 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.

■ APPLICATION NOTE
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.
