Product Summary

The PGA4311U is a high–performance, 4-channel audio volume control designed for professional and high-end consumer audio systems. Using high performance operational amplifier stages internal to the PGA4311U yields low noise and distortion, while providing the capability to drive 600Ω loads directly without buffering. The applications of the PGA4311U are audio amplifiers, mixing consoles, multi–track recorders, broadcast studio equipment, musical instruments, effects processors, A/V receivers, car audio systems.
