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 ±15V 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 600loads 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
PGA2310 devices.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate
precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to
damage because very small parametric changes could cause the device not to meet its published specifications.
