The TL4581 is a dual operational amplifier that has been designed optimally for audio applications, such as improving tone control. It offers low noise, high-gain bandwidth, good slew, and high output current drive for driving capacitive loads. These features make the TL4581 ideally suited for audio applications, such as audio preamps and active filters. When high output current is required, the TL4581 also can be used as a headphone amplifier.
