DESCRIPTION
The ADS1252 is a precision, wide dynamic range,
delta-sigma, Analog-to-Digital (A/D) converter with
24-bit resolution operating from a single +5V supply.
The delta-sigma architecture is used for wide dynamic
range and to guarantee 24 bits of no missing code
performance. An effective resolution of 19 bits (2.5ppm
of rms noise) is achieved for conversion rates up to
40kHz.
The ADS1252 is designed for high-resolution mea-
surement applications in cardiac diagnostics, smart
transmitters, industrial process control, weigh scales,
chromatography, and portable instrumentation. The
converter includes a flexible, two-wire synchronous
serial interface for low-cost isolation.
The ADS1252 is a single-channel converter and is
offered in an SO-8 package.
APPLICATIONS
q CARDIAC DIAGNOSTICS
q DIRECT THERMOCOUPLE INTERFACE
q BLOOD ANALYSIS
q INFRARED PYROMETER
q LIQUID/GAS CHROMATOGRAPHY
q PRECISION PROCESS CONTROL
