Using high performance operational amplifier stages internal to the PGA2310 yields low noise and distortion, while providing the capability to drive 600-Ω loads directly without buffering. The ability to operate from ☑5-V analog power supplies enables the PGA2310 to process input signals with large voltage swings, thereby preserving the dynamic range available in the overall signal path. The PGA2310 is a high-performance, stereo audio volume control designed for professional and high-end consumer audio systems.
