24-Bit, 40kHz

ANALOG-TO-DIGITAL CONVERTER

DESCRIPTION

FEATURES

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.

● 24 BITS NO MISSING CODES

● 19 BITS EFFECTIVE RESOLUTION UP TO

40kHz DATA RATE

● LOW NOISE: 2.5ppm

● DIFFERENTIAL INPUTS

● INL: 0.0015% (max)

● EXTERNAL REFERENCE

● POWER-DOWN MODE

● SYNC MODE

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.

APPLICATIONS

● CARDIAC DIAGNOSTICS

The ADS1252 is a single-channel converter and is

offered in an SO-8 package.

● DIRECT THERMOCOUPLE INTERFACE

● BLOOD ANALYSIS

● INFRARED PYROMETER

● LIQUID/GAS CHROMATOGRAPHY

● PRECISION PROCESS CONTROL
