Misalai ne DAC?

Mai huwa DAC?

Gistarsa na Digital-to-Analog Converters

Digital-to-Analog Converter (DAC), kuma ake kira D/A converter, yana nufin DAC. Wani wurare ce wanda yake aiki da gaba daban-daban da suka zama digital zuwa analog. DAC yana cikakken farko biyu: network mai girgirsa, operational amplifier, reference power supply, da analog switch.

Prinsipin Aiki

DAC yana cikakken digital registers, analog electronic switches, weighted-resistor networks, power amplifiers, da reference voltage sources (ko constant current sources). An sanar da adadin digital don digital storage ya kontrola lokacin da analog electronic switches ke faru, wanda yake amfani da weighted-resistor network a wurare da digit ita 1 ta gina amfani da current value da ya dace da position weight. Power amplifier tana bukatar da cikakken binciken har da kowane current value don tabbatar da shi zuwa voltage values.

Aikin Amfani

An yi amfani da DACs a matsayin output channels a process control computer systems, suna haɗa da actuators don samun inganci na al'adu na ƙasar. Kuma, an yi amfani da DAC circuits a kawar da digital-to-analog converters wadanda suke amfani da feedback technology.

Kategorizaciya

An fi sani ƙarin nau'o'i na DACs, hukuma parallel comparison type, integration type, da ∑-Δ type. Kowane ƙarin yana da muhimmanci da amfani da shi. Misali, parallel comparison type DAC shine mafi kyau, amma ba za a iya samun high resolution ba; integration type ADC yana daidaita wa a low-speed, precision measurement fields; ∑-Δ type ADC yana amfani da incremental coding, wanda yake daidaita wa a high-speed conversion scenarios.

Indikatar Tattalin Arziki

Indikatar tattalin arziki na DAC sun hada da bits, resolution, conversion accuracy, da conversion speed. Bits na neman rayuwar da minimum da maximum values da DAC zan iya nuna da analog quantities. Resolution na neman abin da mafi kyau da DAC zan iya koyar da shi a analog quantity, kawai a kayayyakin least significant bits (LSB). Conversion accuracy na neman cin bayanannin actual value da analog quantity da DAC ya faru da theoretical value. Conversion speed na neman lokaci da DAC ya faru a kan conversion.

Tsunani na Tattalin Arziki

Daga tsunan digital technology, DACs suna zama masu integration da advanced a tattalin arziki. A gaba, DACs zan iya ci gaba da hankali masu high speed, high precision, da low power consumption don samun buƙata da ƙarin yanayi.

Sauran, digital-to-analog converters suna da muhimmanci a wurare da modern control, communication, da detection fields. Daga tsunan tattalin arziki, performance na DACs zan iya zama mafi kyau, kuma amfani da shi zan iya zama ƙarin masu faɗa.
