advertisement True Rail-to-Rail, High Input Impedance ADC Simplifies
Precision Measurements вЂ“ 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 LTC2449вЂ™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 speciп¬Ѓcations hold for all speedsвЂ”only the
resolution changes. Such persistent high performance
simpliп¬Ѓes 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 …
