DESCRIPTION
P5273 is intended for low cost V.90 and V.92
(56kbps)
modems
and
other
high-speed
applications where low distortion at moderate
power levels and very low voiceband frequencies is
required.
P5273 is offered as a direct replacement for
2811B, ATS-273/ATS-273B and LCT0035A in
existing circuits without changes to matching
components.
P5273 uses patented design and construction
methods to achieve excellent signal performance
and safety isolation to international standards.
P5273 is certified to IEC 60950 and UL 60950.
P5273 is a UL Recognized Component and is
supported by an IEC CB certificate. The part is
completely lead-free, compliant with RoHS
Directive 2002/95/EC, and suitable for lead-free
and conventional processing.
FOR NEW DESIGNS
P5233 IS RECOMMENDED
