The μPC451A is a dual operational amplifier designed for single power supply operation. Main 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 utilizing Class C push-pull circuit with 50μA (TYP. ) constant current, and low current consumption. In addition, this amplifier supports both positive and negative power supply and can be used in various amplifier circuits. The μPC1251A which is a dual type with the same circuit configuration is also available under this series of operational amplifiers.
