Title: Sigma-Delta ADCs and DACs Application Note (AN-283) Author: Analog Devices, Inc. Created Date: 0-01-01T00:00:00Z
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.
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.
The STM32F37/38xxx microcontrollers combine a 32-bit Arm® Cortex®-M4 core with a DSP and FPU instructions running at 72 MHz with advanced analog peripherals. 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 ...
INTRODUCTION. Tutorial MT-022 discussed the basics of Σ-Δ ADCs. In this tutorial, we will look at some of the more advanced concepts including idle tones, multi-bit Σ-Δ, MASH, bandpass Σ-Δ, as well as some example applications. IDLE TONE CONSIDERATIONS.
The sigma-delta ADC exhibits excellent differential and integral linearity due to the linearity of the 1 bit quantizer and DAC, and no trimming is required as in other ADC architectures.
