Mikrocontrollerek tein include Analoge to -Digital Converters (ADC) and Digital- to -Analog Converters (DAC) to interface with real- world signals. Understanting how these encents work i essential for designing effective etuic systems. Tiss guide provides a clear overview of ADC and DAC operations in microcolllers.
Mi van?
An ADC converts an analoge voltage signal into a digitál value that a microcontroller can process. It samplets the input voltage at regular intervals and quantzes it into disperté levels based od od its resolutionn, typically expressed in bits.
A deterutión meghatározza a number of discept leveles the ADC can produce. For example, a 10- bit ADC has 1024 szint, laving for more precise measurements. Te concenting rate indicates how spagently the ADC capture inputs.
How does an ADC work?
Az ADC processzek közé tartozik a következő három fő lépés: mintavevő, kvantitatív, and encoding. Ez a mikrocontroller read tis digitál érték for further proceing.
Mi ez a DAC?
A DAC előadja, hogy ez a reverse operation of an ADC. It converts a digitál value into an analogg voltage or regult signal. DAC ause when a microcontroller needs to generate analogs signals, such a as audio or control voltages.
- Egy DAC-s?
A DAC egy digitált input, usually in binary form, and convert it into a administral analoge voltage. This process contingvess selectingting a voltage leavl concerdingig to the digitál value and outputting it approvide gh a resistor network or other circitry.
