  Power Conversion, Measurement and Pulse Circuits &mdash AN113
  PDF, 692 Kb, File published: Aug 7, 2007
  This ink marks LTC’s eighth circuit collection publication.1 We are continually surprised, to the point of near mystification, by these circuit amalgams seemingly limitless appeal. Reader requests ascend rapidly upon publication, remaining high for years, even decades. All LTC circuit collections, despite diverse content, share this popularity, although just why remains an open question. Why is it? Perhaps the form; compact, complete, succinct and insular. Perhaps the freedom of selection without commitment, akin to window shopping. Or, perhaps, simply the pleasure of new recruits for the circuit aficionados intellectual palate. Locally based electrosociolgists, spinning elegantly contrived theories, offer explanation, but no convincing evidence is at hand. What is certain is that readers are attracted to these compendiums and that calls us to attention. As such, in accordance with our mission to serve customer preferences, this latest collection is presented. Enjoy.

  True Rail-to-Rail, High Input Impedance ADC Simplifies Precision Measurements &mdash DN400

  advertisement True Rail-to-Rail, High Input Impedance ADC Simplifies
  Precision Measurements – Design Note 400
  Mark Thoren
  Introduction
  High input impedance and a wide input range are two
  highly desirable features in a precision analog-to-digital
  converter, and the LTCВ®2449 delta-sigma ADC has both.
  With just a few external components, the LTC2449 forms
  an exceptional measurement system with very high input
  impedance and an input range that extends 300mV beyond
  the supply rails.
  A designer may trade off the LTC2449’s 200nV resolution
  for faster conversion rates, but otherwise the LTC2449
  requires few to no performance tradeoffs. It simultaneously achieves 1ppm linearity (Figure 2), 200nV input
  resolution and a 5V input span. Ten п¬Ѓlter oversample
  ratios are available, providing data rates from 6.8 samples
  per second to 3500 samples per second. Normal mode
  rejection of 50Hz and 60Hz is better than 87dB in the 6.8sps
  mode. All DC specifications hold for all speeds—only the
  resolution changes. Such persistent high performance
  simplifies the design of otherwise challenging applications, such as 6-digit voltmeters, sensor interfaces, and industrial control. In addition, the LTC2449 digital
  interface and timing are extremely simple, and the No
  Latency architecture eliminates concerns about п¬Ѓlter …

  DESIGN FEATURES Fast CMOS Op Amp Challenges
  Bipolar Amps on All Key Specs
  by John Wright and Glen Brisebois
  Introduction
  The LTC6241 dual and LTC6242
  quad CMOS op amps compete headon with bipolar op amps in noise,
  speed, offset voltage, and offset drift,
  while maintaining superior low input
  bias and noise current. Crucial advances in these amplifiers’ parameters
  translate to tighter system specs,
  lower complexity, and a wider supply
  voltage operating range than previous CMOS op amps. These extremely
  low input bias current op amps are
  optimized for high impedance transducer applications such as photodiode
  transimpedance amplifiers, TIAs,
  though they are also well suited to a
  variety of precision applications.
  The LTC6241 and LTC6242 do
  not employ complicated post-package schemes to reduce offset voltage,
  yet their 125ВµV offset voltage and
  2.5ВµV/В°C offset drift are among the
  best CMOS amplifiers available. The
  18MHz gain bandwidth and very low …
