AT4558
Dual Operational Amplifier for Audio Features
˙Operating Voltage : ±1.5~±8V or 3~16V ˙Large DC Voltage Gain: 100 dB ˙High input Resistance :0.8MΩ ˙Low Input Offset Voltage:0.7mV ˙Bandwidth(unity gain):3MHz ˙Bipolar Technology
Description
The AT4558 consists of two 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 AT4558 can be directly operated +5V power supply, which is normally used in digital systems.
