Implementation of 12-bit delta-sigma DAC with MSC12xx controller Introduction Digital-to-analog converters (DACs) are usually used as an interface between digital systems and continuous analog circuitry. To choose the type of DAC best suited for an application, the designer must consider many important performance measures.
The Cortex®-M4 core includes a precise 16‐bit sigma‐delta ADC. This application note outlines the main features of the SDADC and shows how the SDADC can be used in some application cases: temperature measurement using PT100, pressure measurement using MPX2102A, wave recorder, and electrocardiogram (ECG) acquisition.
31 sty 2003 · Modern Sigma-delta converters offer high resolution, high integration, low power consumption, and low cost, making them a good ADC choice for applications such as process control, precision temperature measurements, and weighing scales.

Sigma-Delta ADCs and DACs. SIGMA-DELTA OVERVIEW. Within the last several years, the sigma delta architecture has become more and more popular for realizing high-resolutionADCs in mixed-signal VLSI processes. Until recently, however, the process technology needed to make these devices commercially viable has not been available.
Digital-to-Analog Converters (DACs or D/As) Introduction What we commonly refer to as a DAC today is typically quite a bit more. The DAC will typically have the converter itself and a collection of support circuitry built into the chip. The first DACs were board level designs, built from discrete components, including
Delta-Sigma Analog-to-Digital Converters. Brief Overview. Vishal Saxena, Boise State University. (vishalsaxena@boisestate.edu) Why larger overlap on SAR and OS? Sometimes oversampling modulators are preferred over SAR. Why? Nyquist rate SAR converters can’s support complete bandwidth due to stringent requirements on Anti-aliasing Filters.
