APA4558
Dual Operational Amplifier
Features
•
Power Supply Range:
- Signal Supply : 3V to 20V
- Dual Supply :
±
1.5V to
±
10V
General Description
The APA4558 consists of two independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a
single power supply up to 20 volts. Operation from
dual power supplies is also possible and the power
supply current drain is essentially independent of the
magnitude of the power supply voltage.
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).
