AN4250, AN4250S, AN6593
Single Low Power Consumption Operational Amplifiers
■ Overview
The AN4250, the AN4250S, and the AN6593 are
single operational amplifiers which can be operated
with very lo w power consumption. Moreover , they ha ve
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.
■ Features
• Wide supply voltage rang (±1V to ±18V)
• Electrical characteristics programmable by set current
• Phase compensation circuit built in
• Output short-circuit protection
• Offset null
