Description

The AT4558 consists of two independent, high

gain, internally compensated amplifiers which

were designed specifically to operate from a

single or split power supply.

Application areas include transducer amplifier,

DC gain blocks and all the conventional

operational amplifier circuits. The AT4558 can

be directly operated +5V power supply, which is

normally used in digital systems.
