The document introduces the features and characteristics of the PGA2310 digitally controlled analog volume controller, including digitally controlled analog volume control, wide gain and attenuation range, low noise and distortion, low crosstalk, noise-free level transitions, power supplies and applications.
The PGA2310 is a high-performance, stereo audio volume control designed for professional and high-end consumer audio systems. It features two independent audio channels controlled via a three-wire serial interface, allowing for connection to various host controllers and support for daisy-chaining multiple devices.
Key characteristics include a wide gain range from +31.5dB to -95.5dB in 0.5dB steps, low noise and distortion with a dynamic range of 120dB, and low interchannel crosstalk of -126dBFS. The device operates from +15V analog power supplies, enabling it to process input signals with large voltage swings while driving 600Ω loads directly.
