1/51 Application Note 2011 ROHM Co., Ltd. 64AN070E 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 .. 4 2 Absolute Maximum Rating .. 5 power supply voltage/operating range of power supply voltage .. 5 Differential input voltage .. 6 Input common-mode voltage .. 7 Input current .. 8 Operating temperature range .. 8 Maximum junction temperature, storage temperature range .. 8 power dissipation (total dissipation).
Each op-amp circuit is composed of five terminals: a power supply terminal on the positive side, a power supply terminal on the negative side, a + input terminal, a - input terminal, and an output terminal. (There are no general terms for the terminals except classifications such as power source, input and output.) Table 1.1.1.
