Product Summary
The PGA2310UA is a high-performance, stereo audio volume control designed for professional and high-end consumer audio systems. The ability to operate from ±15V analog power supplies enables the PGA2310UA to process input signals with large voltage swings, thereby preserving the dynamic range available in the overall signal path. Using high performance operational amplifier stages internal to the PGA2310UA yields low noise and distortion, while providing the capability to drive 600Ω loads directly without buffering. The three-wire serial control interface allows for connection to a wide variety of host controllers, in addition to support for daisy-chaining of multiple PGA2310PA devices. The applications of the PGA2310UA include audio amplifiers, mixing consoles, multi-track recorders, broadcast studio equipment, musical instruments, effects processors, a/v receivers and car audio systems.
