24-Bit, 20kHz, Low-Power  
ANALOG-TO-DIGITAL CONVERTER  
DESCRIPTION  
FEATURES  
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.  
24 BITS—NO MISSING CODES  
19 BITS EFFECTIVE RESOLUTION UP TO  
20kHz DATA RATE  
LOW NOISE: 1.5ppm  
DIFFERENTIAL INPUTS  
INL: 15ppm (max)  
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.  
EXTERNAL REFERENCE (0.5V to 5V)  
POWER-DOWN MODE  
SYNC MODE  
LOW POWER: 8mW at 20kHz  
5mW at 10kHz  
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).
