1/51 Application Note 2011 ROHM Co., Ltd. Op-Amp/ Comparator Application Note Operational amplifier , Comparator (Tutorial) This application note explains the general terms and basic techniques that are necessary for configuring application circuits with op-amps and comparators. Refer to this note for guidance when using op-amps and comparators. a Contents 1 What Is Op-Amp/ Comparator ? ........................................ ........................................ ........................................ ........................................ .......... 2 What is op-amp? ........................................ ........................................ ........................................ ........................................ ......................... 2 What is Comparator ? ........................................ ........................................ ........................................ ........................................ .................. 3 Internal circuit configuration of op-amp/ Comparator .

potential → High level output. When the -input terminal potential > the + input terminal potential → Low level output. The major difference between op-amps and comparators is whether or not the phase compensation capacitance exists. Since op-amps configure and utilize a negative feedback circuit, they require phase compensation capacitance to
