INTRODUCTION
Application Note 87 is the fifth in a series that excerpts
useful circuits from Linear Technology magazine to preserve them for posterity. This application note highlights
data conversion, interface and signal conditioning circuits
from issue VI:1 (February 1996) through issue VIII:4
(November 1998). Like its predecessor, AN67, this Application Note includes circuits for high speed video, interface and hot swap circuits, active RC and switched capacitor filter circuitry and a variety of data conversion and instrumentation circuits. There are also several circuits
that cannot be so neatly categorized. So, without further
ado, IвЂ™ll let the authors describe their circuits.
Note: Article Titles appear in this application note exactly
as they originally appeared in Linear Technology magazine. This may result in some inconsistency in the usage
of terminology. TABLE OF CONTENTS

A Low Power, High Output Current Dual CFA Makes xDSL Line
Driving Clean and Easy вЂ“ Design Note 187
Adolfo A Garcia
Introduction
Driving the balanced lines of high speed modems has
become a very popular application for high speed,
high output current, dual operational ampliп¬Ѓers. High
ampliп¬Ѓer speed is required to faithfully process signal
passbands of at least 1MHz bandwidth, and high
output currents are required to meet peak drive levels
into 100О© or 135О© termination. Taking into account
peak-to-average signal ratios in these applications,
Table 1 summarizes peak voltage/current drive levels
required by current xDSL systems. The peak voltage
and current drive values shown are for ADSL systems
with 100О© termination and HDSL/HDSL2 systems with
135О© termination.
