Overview
Description
μPC1251, μPC358 are dual operational amplifiers designed to operate on a single power supply. The features include low-voltage operation, a common-mode input voltage that ranges 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 50μA (TYP.) constant current, and a low current consumption. In addition, 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 a wide operating ambient temperature use due to its temperature expansion type, while μPC358 is for general-purpose usage. A DC parameter selection that is compatible to operational amplifiers is also available. μPC451, μPC324 which are quad types with the same circuit configuration are also available under this series of operational amplifiers.

What is the difference between general use and industrial use?
... with operational amplifiers/comparators for industrial use, all devices are subject to testing with all test items. (Example) Single-power-supply dual operational amplifier For general use (UPC358G2) : Ambient operating temperature range: -20 to +80°C For industrial use(UPC1251G2) : Ambient operating temperature range: -40 to +85°C (2005/09)
