AN4250

AN4250, AN4250S, AN6593 Single Low Power Consumption Operational Amplifiers s Overview The AN4250, the AN4250S, and the AN6593 are single operational amplifiers which can be operated with very low power consumption. Moreover, they have wide range (± 1V to ± 18V)of supply voltage, and electrical characteristics such as power consumption and input bias current can be programmed according to the current value set by outer resistor. They are suitable for applications to various electronic circuits such as portable electronic equipments operated by the battery.
