Single Power Supply Dual Operational Amplifiers
DESCRIPTION
R03DS0144EJ0100
Rev.1.00
2019.1.17
μPC1251, μ PC358 are dual operational amplifiers designed to operate on a single power supply. The features
include low-voltage operation, a common-mode input voltage that range from V
−
(GND) level, an output from
a V
−
(GND) level that is determined by the output stage of class C push-pull circuit and a 50 μA(TYP.) constant
current, and a low current consumption.
In addition to that, this amplifier can also operate in both positive and negative power supply and can be used
extensively in various amplifier circuits.
The μPC1251 is suited for wide operating ambient temperature use due to its temperature expansion type,
while μPC358 is for general purposes usage.
A DC parameter selection that is compatible to operational amplifiers is also available.
μPC451, μ PC324 which are quad types with the same circuit configuration are also available under this series
of operational amplifiers.

【Note】
1.
Note that reverse connections of the power supply may damage the ICs.
2.
The input voltage is allowed to input without damage or destruction independent of the magnitude of V+.
Either input signal is not allowed to go negative by more than 0.3 V. In addition, the input voltage that
operates normally as an operational amplifier is within the Common Mode Input Voltage range of an
electrical characteristic.
3.
A range where input voltage can be applied to an output pin externally with no deterioration or damage to
the feature (characteristic). The input voltage can be applied regardless of the electric supply voltage. This
specification which includes the transition state such as electric power ON/OFF must be kept.
4.
This is the value when the glass epoxy substrate (size: 100 mm x 100 mm, thickness: 1 mm, 15% of the
substrate area where only one side is copper foiled is filling wired) is mounted.
Note that restrictions will be made to the following conditions for each product, and the derating ratio
depending on the operating ambient temperature.

Short circuits from the output to V

can cause destruction. Pay careful attention to the total power dissipation
by not exceeding the absolute maximum ratings,

【Note】
6.
The absolute value of the input bias current is small, thus the direction of the current flowing from the inside
of the IC may be reversed due to variations in the product during high temperature.
7.
This is a current that flows in the internal circuit. This current will flow irrespective of the channel used.
