DESCRIPTION
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.
