MacP331 Analog-to-Digital Converters
Microchip na MCP331 na'urori suna da cikakken daban-daban shigarwar, high performance, da kuma low ikon amfani a cikin wani karamin kunshin
Microchip & rsquo; s MCP331x na'urorin sun kasance guda ɗaya ƙare 16-bit, 14-bit, da 12-bit, guda-tashar 1 Msps da 500 kSPS analog-to-digital converters (ADCs) tare da amfani da low amfani da high performance, ta yin amfani da gajeren kimanin rajista (SAR). Na'urorin suna aiki tare da mahimmanci 2.5 V zuwa 5.1 V (VREF) wanda ke tallafawa fadi da dama na shigar da cikakken sikelin daga 0 V zuwa VREF. Tsarin lantarki na tunani yana mai zaman kanta daga wutar lantarki na analog (AVDD) kuma ya fi AVDD. Ana samar da samfur ta hanyar sauƙi mai sauƙi mai amfani SPI mai dacewa 3-waya ke dubawa. Wadannan na'urorin suna da 1 M samfurori / na biyu, ɗaya tashar shigarwa, amfani da ƙasa maras nauyi (0.8 & micro; A jiran aiki, 1.6 mA na al'ada aiki), kuma ana bayar da su a cikin wani nau'in MSOP mai lamba 10. Cikin MCP331 ADCs yana nuna cikakken shigarwar daban-dabam, babban aiki, da kuma rageccen ikon amfani a cikin karamin kunshin. Wannan fasali mai kyau ya sanya waɗannan samfurori da suka dace don tsarin batir da aikace-aikace na sayen nesa irin su kayan aikin likita, ikon motsa jiki, kayan gwajin, da kayan wuta.

- ADC gyaran kai don ƙaddara, riba, da kurakuran layi:
- A lokacin ƙarfin wuta (atomatik)
- On-buƙata ta mai amfani & rsquo; s umurnin yayin aiki na al'ada
- AEC-Q100 ya cancanta:
- Yawan yanayin zafi 1: -40 & deg; C zuwa + 125 & deg; C
- High-daidaito data saye
- Kayan aikin likita
- Matakan gwaji
- Gudanar da tsarin baturi na lantarki
- Umurnin sarrafa motoci
- Kayayyakin aikace-aikacen wutar lantarki
- Batir-powered kayan aiki
