NJU7036
High Output Current, Single Supply, Rail-to-Rail Output
Dual CMOS Operational Amplifier
I
GENERAL DESCRIPTION
The NJU7036 is a Rail-to-Rail Output operational amplifier of single power supply operation.
It has the characteristic of high power output current and is suitable for driving heavy loads such as a small motor, LED, and speakers.
It has up to 0.15 V saturation voltages at an output current of 250mA.
Therefore it can reduce the electric power loss in IC and contribute to the design of low power consumption.
Moreover, micro leadless package (PCSP20-E3) is available for it, so that it can also contribute to the miniaturization of the equipment.

VDD terminal, VSS terminal and OUTPUT terminal use two or more pins respectively and are lowering terminal resistance.
You shall connect each two pins (VDD, VSS and OUTPUT) with the same electric potential.
When only one pin is used, the internal terminal resistance becomes high and the maximum output voltage declines.

Application Notes
•
Package Power, Power Dissipation and Output Power
IC is heated by own operation and possibly gets damage when the junction power exceeds the acceptable value called Power
Dissipation P
D
. The dependence of the NJU7036 P
D
on ambient temperature is shown in Fig 1. The plots are depended on following
two points. The first is P
D
on ambient temperature 25℃, which is the maximum power dissipation. The second is 0W, which means
that the IC cannot radiate any more. Conforming the maximum junction temperature Tjmax to the storage temperature Tstg derives
this point. Fig.1 is drawn by connecting those points and conforming the P
D
lower than 25℃ to it on 25℃. The P
D
is shown following
formula as a function of the ambient temperature between those points.

Where,
θja
is heat thermal resistance which depends on parameters such as package material, frame material and so on.
Therefore, P
D
is different in each package.
While, the
actual measurement of dissipation power on NJU7036 is obtained
using following equation.
(Actual Dissipation Power) = (Supply Voltage V
DD
) X (Supply Current I
DD
) – (Output Power Po)
The NJU7036 should be operated in lower than P
D
of the actual dissipation power.
To sustain the steady state operation, take account of the Dissipation Power and thermal design.

•
Thermal Protection
The NJU7036 is designed with Thermal Shut Down (TSD) circuitry that protects itself from damage caused by overload
condition. The TSD circuitry is operated when the junction temperature reaches approximately 180℃, and the
actual
measurement of dissipation power is reduced by
the stopped output current. When the junction temperature cools to
approximately 150℃, the output circuitry is automatically re-enabled. Continuously running the NJU7036 into the thermal
shutdown possibly damages device since the TSD circuit doesn’t have active cooling function such as heat sinking.
To sustain
the steady state operation,
the NJU7036 should be operated in lower than the
Dissipation Power of
the
actual dissipation
power.
•
Current Limit
The NJU7036 should be operated in lower than 500mA of output current.
The NJU7036 has current limiting circuitry that
prevents from exceeding output current caused by grounding in order to enhance the safety of operation. The circuitry limits
output current to approximately 1A.
Although the output current is lower than 500mA, the device possibly gets damage duo to
heating by output current.
To sustain the steady state operation,
the NJU7036 should be operated in lower than 500mA of output
current and lower than the
Dissipation Power of
the
actual dissipation power.
