Description

The AT5558 consists of four 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 AT5558 can
be directly operated +5V power supply, which is
normally used in digital systems.
