SBAS458 – JUNE 2009 18-Bit Analog-to-Digital Converter For Bridge Sensors 2 • 18-Bit Noise-Free Resolution The ADS1130 is a precision, 18-bit analog-to-digital converter (ADC). With an onboard low-noise gain • Complete Front-End for Bridge Sensor amplifier, onboard oscillator, and precision 18-bit • Onboard Gain of 64 delta-sigma ADC, the ADS1130 provides a complete • Onboard Oscillator front-end solution for bridge sensor applications • Selectable 10SPS or 80SPS Data Rates including weigh scales and strain gauges. • Simultaneous 50Hz and 60Hz Rejection at The low-noise amplifier has a gain of 64, supporting a 10SPS full-scale differential input of ±39mV. The delta-sigma ADC has 18-bit effective resolution and is comprised • External Voltage Reference up to 5V for of a third-order modulator and fourth-order digital Ratiometric Measurements filter. Two data rates are supported: 10SPS (with both • Simple, Pin-Driven Control 50Hz and 60Hz rejection) and 80SPS. The ADS1130 • Two-Wire Serial Digital Interface can be put into a low-power standby mode or shut off completely in power-down mode. • Tiny TSSOP-16 Package • Supply Range: 2.7V to 5.3V All of the features of the ADS1130 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 • Weigh Scales and other microcontrollers. • Strain Gauges The ADS1130 is available in a TSSOP-16 package and is specified for operation from –40°C to +85°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
