вЂњEasy DriveвЂќ Delta-Sigma Analog-to-Digital Converters
Cancel Input Current Errors вЂ“ Design Note 368
Mike Mayes
Introduction
It is now possible to place large RC networks directly in front of high resolution в€†ОЈ analog-to-digital
converters without degrading their DC accuracy
(see Figure 1). The LTC В®248x family of converters
solves this problem with Easy Driveв„ў technology,
a fully passive sampling network that automatically
cancels the differential input current. Easy Drive
technology does not use on-chip buffers, which
compromise performance (see What is Wrong with
On-Chip Buffers?), but instead uses a new architecture
that maintains 0.002% full-scale error with input RC
networks up to 100kО© and 10ОјF. This new technology
offers many advantages over previous generation в€†ОЈ
ADCs: Rail-to-rail common mode input range Direct digitization of high impedance sensors Elimination of sampling spikes seen at the ADC input
pins Simple external lowpass п¬Ѓltering Noise/power reduction Cancellation of external RC settling errors Easy interface to external ampliп¬Ѓers Removal of transmission line effects for remote
sensors

High Impedance Sensors вЂ“ Design Note 379
Mark Thoren
Delta-sigma ADCs, with their high accuracy and high noise
immunity, are ideal for directly measuring many types
of sensors. Nevertheless, input sampling currents can
overwhelm high source impedances or low-bandwidth,
micropower signal conditioning circuits. The LTCВ®2484
family of delta sigma converters solves this problem by
balancing the input currents, thus simplifying or eliminating the need for signal conditioning circuits.
A common application for a delta-sigma ADC is thermistor
measurement. Figure 1 shows the LTC2484 connections
for direct measurement of thermistors up to 100kО©. Data
I/O is through a standard SPI interface and the sampling
current in each input is approximately:
