DESCRIPTION
The PGA4311 is a high–performance, 4-channel audio
volume control designed for professional and high-end
consumer audio systems. Using high performance
operational amplifier stages internal to the PGA4311
yields low noise and distortion, while providing the
capability to drive 600Ω loads directly without buffering.
The 3-wire serial control interface allows for connection
to a wide variety of host controllers, in addition to
support for daisy-chaining of multiple PGA4311
devices.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to ob-
serve 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.
(1) Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability.
