General Description

The Delta Sigma Analog to Digital Converter (ADC_DelSig) provides a low-power, low-noise front end for precision measurement applications. You can use it in a wide range of applications, depending on resolution, sample rate, and operating mode. It can produce 16-bit audio; high speed and low resolution for communications processing; and high-precision 20-bit low-speed conversions for sensors such as strain gauges, thermocouples, and other high-precision sensors. When processing audio information, the ADC_DelSig is used in a continuous operation mode. When used for scanning multiple sensors, the ADC_DelSig is used in one of the multi-sample modes. When used for single-point high-resolution measurements, the ADC_DelSig is used in single-sample mode.
