www.datasheet4u.com SINGLE POWER SUPPLY DUAL OPERATIONAL AMPLIFIERS
<R> DESCRIPTION
The μ PC1251GR-9LG, μ PC1251MP-KAA, μ PC358GR-9LG are dual operational amplifiers which are designed to
operate for a single power supply. It includes features of 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, this can operate at both positive and negative power supply and it can be extensively used in various
amplifier circuits.
The μ PC1251GR-9LG, μ PC1251MP-KAA which expands temperature type is suited for wide operating ambient
temperature use, and μ PC358GR-9LG is used for general purposes.
A DC parameter selection that is compatible to operational amplifiers is also available.
μ PC451GR-9LG, μ PC324GR-9LG which are quad types with the same circuit configuration are also available as
series of operational amplifiers.

<R> PRECAUTIONS FOR USE
O The process of unused circuits
If there is an unused circuit, the following connection is recommended.

O Ratings of input/output pin voltage
When the voltage of input/output pin exceeds the absolute maximum rating, it may cause degradation of
characteristics or damages, by a conduction of a parasitic diode within an IC. In addition, when the input pin may be
lower than V−, or the output pin may exceed the power supply voltage, it is recommended to make a clump circuit by
a diode whose forward voltage is low (e.g.: Schottky diode) for protection.
O Range of common-mode input voltage
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+ − 1.5 (V) (TA = 25°C)
During designing, temperature characteristics for use with allowance.
O The maximum output voltage
The range of the TYP. value of the maximum output voltage when the supply voltage does not meet the condition
of electrical characteristics is as follows:
VOm+ (TYP.): V+ − 1.5 (V) (TA = 25°C), VOm− (TYP.) (IO SINK ≤ 50 μA): Approx. V− (V) (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 (VOm+ − VOm−) becomes narrow when an output current
increases.
O Operation of output
This IC consist an output level of a class C push-pull. Therefore, when a load resistance is connected to the
midpoint potential of V+, V−, a crossover distortion occurs at the transition state of output current flow direction
(source, sink).
O Handling of ICs
When stress is added to ICs due to warpage or bending of a board, the characteristic fluctuates due to
piezoelectric effect. Therefore, pay attention to warpage or bending of a board.
