SBAS366A–OCTOBER 2006–REVISED JULY 2007  
20-Bit Analog-to-Digital Converter  
For Bridge Sensors  
1
FEATURES  
DESCRIPTION  
2
•
Complete Front-End for Bridge Sensor  
Onboard PGA with Gain of 64 or 128  
Onboard Oscillator  
The ADS1230 is a precision 20-bit analog-to-digital  
converter (ADC). With an onboard low-noise  
programmable gain amplifier (PGA), onboard  
oscillator, and precision 20-bit delta-sigma ADC, the  
ADS1230 provides a complete front-end solution for  
bridge sensor applications including weigh scales,  
strain gauges, and pressure sensors.  
•
•
•
RMS Noise:  
40nV at 10SPS (G = 128)  
88nV at 80SPS (G = 128)  
•
•
•
18-Bit Noise-Free Resolution  
The low-noise PGA has a gain of 64 or 128,  
supporting a full-scale differential input of ±39mV or  
±19.5mV, respectively. The delta-sigma ADC has  
20-bit effective resolution and is comprised of a  
3rd-order modulator and 4th-order digital filter. Two  
data rates are supported: 10SPS (with both 50Hz and  
60Hz rejection) and 80SPS. The ADS1230 can be  
clocked by the internal oscillator or an external clock  
source. Offset calibration is performed on-demand,  
and the ADS1230 can be put in 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  
Tiny 16-pin TSSOP Package  
Supply Range: 2.7V to 5.3V  
–40°C to +85°C Temperature Range  
All of the features of the ADS1230 are 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.  
APPLICATIONS  
•
•
•
•
Weigh Scales  
Strain Gauges  
Pressure Sensors  
Industrial Process Control  
The ADS1230 is available in a TSSOP-16 package  
and is specified from –40°C to +85°C.
