APC558
Dual Operational Amplifier
Features
•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
General Description
The APC558 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 APC558 can be directly operated from the standard +5V power supply voltage which is normally used in digital systems.)
