An operational amplifier/comparator for general use is recommended for use in consumer products, whereas one for industrial use is recommended for use in industrial equipment. The latter are designed for use in sets that operate in difficult environments and therefore have a wider ambient operating temperature range than the former. Moreover, 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
