Outline
This IC is a dual-type operational amplifier, with two built-in operational amplifiers, and achieves extremely low offset voltage with a single power supply. The input offset voltage and the input offset voltage temperature drift of this operation amplifier are one digit less than those of our conventional products. A single power supply can be used, so there is no need to create a mid-point potential, and it can be operated with the voltage from two batteries. Due to the single power supply, low current consumption, and low offset voltage, two batteries can be used for operation, making it appropriate for equipment that amplifies the very small signal of portable equipment.
