ADS1253  
ADS1253  
SBAS199 – MAY 2001  
24-Bit, 20kHz, Low Power  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
The ADS1253 is a precision, wide dynamic range, delta-  
sigma, Analog-to-Digital (A/D) converter with 24-bit reso-  
lution operating from a single +5V supply. The delta-sigma  
architecture is used for wide dynamic range and to guarantee  
24 bits of no missing codes performance. An effective  
resolution of 19 bits (1.8ppm of rms noise) is achieved for  
conversion rates up to 20kHz.  
24 BITS—NO MISSING CODES  
19 BITS EFFECTIVE RESOLUTION UP TO  
20kHz DATA RATE  
LOW NOISE: 1.8ppm  
FOUR DIFFERENTIAL INPUTS  
INL: 15ppm (max)  
The ADS1253 is designed for high-resolution measurement  
applications in cardiac diagnostics, smart transmitters, in-  
dustrial process control, weight scales, chromatography, and  
portable instrumentation. The converter includes a flexible,  
two-wire synchronous serial interface for low-cost isolation.  
EXTERNAL REFERENCE (0.5V to 5V)  
POWER-DOWN MODE  
SYNC MODE  
LOW POWER: 8mW at 20kHz  
5mW at 10kHz  
The ADS1253 is a four-channel converter and is offered in  
an SSOP-16 package.
