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 a pplications to various
electronic circuits such as portable electronic
equipments operated by the battery.
s Features
Wide supply voltage rang (
1V to
18V)
Electrical characteristics programmable by set current
Phase compensation circuit built in
Output short-circuit protection
