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

The LT1167: Single Resistor Sets the Gain of the Best
Instrumentation Amplifier вЂ“ Design Note 182
Alexander Strong and Kevin R. Hoskins
Introduction
Linear TechnologyвЂ™s next generation LTВ®1167 instrumentation ampliп¬Ѓer uses a single resistor to set gains
from 1 to 10,000. The single gain-set resistor eliminates
expensive resistor arrays and improves VOS and CMRR
performance. Careful attention to circuit design and
layout, combined with laser trimming, greatly enhances
the CMRR, PSRR, gain error and nonlinearity, maximizing application versatility. The CMRR is guaranteed to
be greater than 90dB when the LT1167вЂ™s gain is set at
1. Total input offset voltage (VOS) is less than 60ОјV at a
gain of 10. For gains in the range of 1 to 100, gain error
is less than 0.05%, making the gain-set resistor tolerance the dominant source of gain error. The LT1167вЂ™s
gain nonlinearity is unsurpassed when compared to
other monolithic solutions. It is speciп¬Ѓed at less than
40ppm when operating at a gain of 1000 while driving
a 2kО© load. The LT1167 is so robust that it can drive
600О© loads without a signiп¬Ѓcant linearity penalty. These
parametric improvements result in an overall gain error
that remains unchanged over the entire input common
mode range and is not degraded by supply perturbations
or varying load conditions. The LT1167 can operate over …

Resolving Very Small Temperature Differences
with the LTC2402 вЂ“ Design Note 257
Derek Redmayne
The LTC В®2402, a 2-channel 24-bit, No Latency
Delta-Sigmaв„ў ADC, is well-suited to differential
temperature sensing using a number of different
sensors. Extremely good matching between channels
allows two absolute temperature measurements to
be compared in order to determine the differential or
gradient between two points. In the circuits shown
below, the LTC2402, with averaging, can resolve a
temperature differential of a few millidegrees, although
in the case of a single-shot pair of readings, a peak error
of 0.05В°C is possible. Independently adjustable full-scale
(FSSET ) and zero-scale (ZSSET ) facilitate 3-or 4-wire
measurements with platinum RTDs and the automatic
sequencing of the two channels makes measurements
across an isolation barrier easier. The no latency feature
of these ADCs also resolves dilemmas associated
with pulsed excitation. The use of pulsed excitation
minimizes or eliminates parasitic thermocouple effects
that can compromise RTD measurements. In addition,
pulsed excitation can reduce standby or average power …

Instrumentation Amplifier

Introduction Circuit Operation
operate near the sensor or circuitвЂ™s
positive supply voltage or ground
(common). Even though the signal
conditioning circuitry need not operate at the extremes of the supply
voltage range, the output voltage swing
of the circuit should be as large as
possible for maximum dynamic range.
The circuit illustrated in Figure 1
achieves high precision performance
while operating from a single 5V
supply. The trick here is to reference
the dual-supply instrumentation
amplifierвЂ™s inputs to a stable midpoint supply and then follow the
instrumentation amplifier with a
single-supply precision operational
amplifier with a rail-to-rail output
stage. This вЂњcompositeвЂќ instrumentation amplifier uses an LT1167 (a high
performance instrumentation amplifier in an SO-8 package) for the input …

DESIGN FEATURES The LT1167: Precision, Low Cost,
Low Power Instrumentation Amplifier
Requires a Single Gain-Set Resistor
by Alexander Strong
Introduction Input Protection The LT1167 is the next-generation
instrumentation amplifier designed
to replace the previous generation of
monolithic instrumentation amps, as
well as discrete, multiple op amp
solutions. Instrumentation amplifiers differ from operational amplifiers
in that they can amplify input signals
that are not ground referenced. The
output of an instrumentation amplifier is referenced to an external voltage
that is independent of the input. Conversely, the output voltage of an op
amp, due to the nature of its feedback, is referenced to the differential
and common mode input voltage.
A separate ground reference and
the high CMRR of the LT1167 instrumentation amplifier reduce the effect
of the input common mode voltage on
the output signal. The closed-loop
gain of an op amp and of most instrumentation amps is set by a resistor
ratio; the gain of the LT1167 is set by
the absolute value of one external …

DESIGN FEATURES New Instrumentation Amplifier: SingleResistor Gain Set and Precision Front
End Make Accuracy Easy
by Glen Brisebois
The LT1168 is a low power,
single-resistor gain-programmable
instrumentation amplifier that is easy
to apply. It is a pin-compatible upgrade
for the AD620 (and the INA118 with a
resistor-value change) and is available in C and I grades. With negligible
60ВµV (Max) offset voltage and ultrahigh 1Tв„¦ input impedance, it can
sense bridges with source impedances
from 10в„¦ to 100k without degrading
the signal. Its 120dB CMRR at 60Hz
(AV = 100V) is achieved even with a 1k
source impedance imbalance. Matching the LT1168вЂ™s CMRR using discrete
op amps would require the use of
0.001% resistors. The LT1168вЂ™s
robust inputs meet IEC1000-4-2
Level 4 ESD tests with the addition of
two external 5k series resistors. These
5k resistors will contribute only a
negligible 6ВµV of DC error. Table 1. Examples of series resistors for precision gain Desired Gain RG
