3 Description
The PGA2310 is a high-performance, stereo audio
volume control designed for professional and high-
end consumer audio systems. The ability to operate
from ±15-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. 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 three-wire serial control
interface allows for connection to a wide variety of
host controllers, in addition to support for daisy-
chaining multiple PGA2310 devices.
