16-Bit Resolution  
The ADS1203 is a delta-sigma (∆Σ) modulator with a  
95dB dynamic range, operating from a single +5V  
supply. The differential inputs are ideal for direct  
connection to transducers or low-level signals. With the  
appropriate digital filter and modulator rate, the device  
can be used to achieve 16-bit analog-to-digital (A/D)  
conversion with no missing codes. An effective  
resolution of 14 bits or SNR of 85dB (typical) can be  
maintained with a digital filter bandwidth of 40kHz at a  
modulator rate of 10MHz. The ADS1203 is designed for  
use in medium- to high-resolution measurement  
applications including current measurements, smart  
transmitters, industrial process control, weigh scales,  
chromatography, and portable instrumentation. It is  
available in an 8-lead TSSOP package. A 16-pin QFN  
(3x3) package will be available soon.
