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
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.
Title: Sigma-Delta ADCs and DACs Application Note (AN-283) Author: Analog Devices, Inc. Created Date: 0-01-01T00:00:00Z
INTRODUCTION. The sigma-delta (Σ-Δ) ADC is the converter of choice for modern voiceband, audio, and high-resolution precision industrial measurement applications. The highly digital architecture is ideally suited for modern fine-line CMOS processes, thereby allowing easy addition of digital functionality without significantly increasing the cost.
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.
How delta-sigma ADCs work, Part 1. By Bonnie Baker. Signal Integrity Engineer. Analog techniques have dominated signal processing for years, but digital techniques are slowly encroaching into this domain. The design of delta-sigma (DS) analog-to-digital converters (ADCs) is approximately three-quarters digital and one-quarter analog.
