APA4558
Dual Operational Amplifier
Features |
General Description |
• !!Power Supply Range:
- Signal Supply : 3V to 20V
- Dual Supply : ± 1.5V to ± 10V
•Large DC Voltage Gain : 100dB
•Large Output Swing : 0V ~ VDD- 1.5V
•Bandwidth(unity gain) : 2MHz
•Internally Frequency Compensated for Unity
Gain
•Low Input Offset Voltage : 1mV
Applications
•!!Amplifiers
•!!Filters
•!!Analog Circuit
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 . )
