DESCRIPTION
The ADS1251 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 features wide dynamic range, and 24 bits of no
missing code performance. Effective resolution of 19 bits
(1.5ppm of rms noise) is achieved at conversion rates up to
20kHz.
The ADS1251 is designed for high-resolution measurement
applications in cardiac diagnostics, smart transmitters, indus-
trial process control, weigh scales, chromatography, and
portable instrumentation. The converter includes a flexible,
2-wire synchronous serial interface for low-cost isolation.
The ADS1251 is a single-channel converter and is offered in
an SO-8 package. It is pin-compatible with the faster ADS1252
(41.7kHz data rate).
APPLICATIONS
q CARDIAC DIAGNOSTICS
q DIRECT THERMOCOUPLE INTERFACES
q BLOOD ANALYSIS
q INFRARED PYROMETERS
q LIQUID/GAS CHROMATOGRAPHY
q PRECISION PROCESS CONTROL
