Block Diagram

The APA4558 consists of two independent , high gain

, internally frequency compensated operational am-

plifiers which were designed specifically to operate

from a single power supply up to 20 volts . Opera-

tion from dual power supplies is also possible and

the power supply current drain is essentially inde-

pendent of the magnitude of the power supply volt-

age .

Application areas include transducer amplifiers , DC

gain blocks and all the conventional OP amplifier

circuits which can be more easily implemented in

single power supply systems . ( For example , the

APA4558 can be directly operated from the standard

+5V power supply voltage which is normally used in

digital systems . )
