Low Distortion, Low Noise Differential Amplifier Drives High
Speed ADCs in Demanding Communications Transceivers
Design Note 366
Cheng-Wei Pei
Introduction
TodayвЂ™s communications transceivers operate at much
higher frequencies and wider bandwidths than those of
the past. Combining this with higher resolution requirements, transceiver design can become daunting. For
engineers designing these systems, small noise and
distortion budgets leave little п¬‚exibility when choosing
system components.
The LTВ®1993-x is designed to meet the demanding
requirements of communications transceiver applications. It can be used as a differential ADC driver or as
a general-purpose differential gain block. For singleended systems, the LT1993-x can replace a transformer
in performing single-ended to differential conversion
without sacriп¬Ѓcing noise or distortion performance.
