DESCRIPTION
The ADS1252 is a precision, wide dynamic range, delta-
sigma, Analog-to-Digital (A/D) converter with 24-bit resolu-
tion operating from a single +5V supply. The delta-sigma
architecture is used for wide dynamic range and to ensure 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 measurement
applications in cardiac diagnostics, smart transmitters, indus-
trial process control, weight scales, chromatography, and
portable instrumentation. The converter includes a flexible,
2-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 INTERFACES
q BLOOD ANALYSIS
q INFRARED PYROMETERS
q LIQUID/GAS CHROMATOGRAPHY
q PRECISION PROCESS CONTROL
