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.
