产品信息
描述The ADS1130 is aprecision, 18-bit analog-to-digital converter (ADC).With an onboard low-noise gain amplifier, onboard oscillator, and precision 18-bitdelta-sigma ADC, the ADS1130 provides a complete front-end solution for bridge sensor applications including weigh scales and strain gauges. The low-noise amplifier has a gain of 64, supporting a full-scale differential input of ±39mV.The delta-sigma 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 ADS1130 can be put into a low-power standby mode or shut off completely in power-down mode. 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 and other microcontrollers. The ADS1130 is available in a TSSOP-16 package and is specified for operation from -40°C to +85°C.特性18-Bit Noise-Free Resolution Complete Front-End for Bridge Sensor Onboard Gain of 64 Onboard Oscillator Selectable 10SPS or 80SPS Data RatesSimultaneous 50Hz and 60Hz Rejection at 10SPS External Voltage Reference up to 5V for Ratiometric Measurements Simple, Pin-Driven Control Two-WireSerial Digital Interface Tiny TSSOP-16 Package Supply Range: 2.7V to 5.3V APPLICATIONS Weigh Scales Strain GaugesAll trademarks are the property of their respective owners.
