SBAS449B –JULY 2009–REVISED SEPTEMBER 2011  
18-Bit Analog-to-Digital Converter  
for Bridge Sensors

FEATURES  
DESCRIPTION  
The ADS1131 is a precision, 18-bit analog-to-digital  
converter (ADC). With an onboard, low-noise  
amplifier, onboard oscillator, precision 18-bit  
delta-sigma (ΔΣ) ADC, and bridge power switch, the  
ADS1131 provides a complete front-end solution for  
bridge sensor applications including weigh scales,  
strain gauges, and load cells.

Complete Front-End for Bridge Sensors  
Available in an SO Package  
Internal Amplifier, Gain of 64  
Internal Oscillator  
Low-Side Power Switch for Bridge Sensor  
18-Bit Noise-Free Resolution  
The low-noise amplifier has a gain of 64, supporting a  
full-scale differential input of ±39mV. The ΔΣ ADC  
has 18-bit effective resolution and is comprised of a  
third-order modulator and fourth-order digital filter.  
Two data rates are supported: 10SPS (with both  
50Hz and 60Hz rejection) and 80SPS. The ADS1131  
can be put into a low-power standby mode or shut off  
completely in power-down mode.  
Selectable 10SPS or 80SPS Data Rates  
Simultaneous 50Hz and 60Hz Rejection at  
10SPS  
•
External Voltage Reference up to 5V for  
Ratiometric Measurements  
•
•
•
•
Simple, Pin-Driven Control  
Two-Wire Serial Digital Interface  
Supply Range: 3V to 5.3V  
The ADS1131 is controlled by dedicated pins; there  
are no digital registers to program. Data are output  
over an easily-isolated serial interface that connects  
directly to the MSP430 and other microcontrollers.  
–40°C to +85°C Temperature Range  
APPLICATIONS  
The ADS1131 is available in an SO-16 package and  
is specified from –40°C to +85°C.
