MCP331 Analog-to-Digital Converters
Zipangizo za MCP za MCP331 zimakhala ndi zosiyana zowonjezera, zopindulitsa kwambiri, komanso mphamvu zochepa mu phukusi laling'ono
Zipangizo za microchip & rsquo; s MCP331x ndi 16-bit, 14-bit, 12-bit, single-channel 1 Msps ndi 500 kSPS osintha-digito (ADCs) omwe ali ndi mphamvu yapamwamba komanso yogwira ntchito, zomangamanga zowerengera (SAR). Zipangizozi zimagwiritsidwa ntchito ndi 2.5 V mpaka 5.1 V kunja (VREF) zomwe zimathandiza zogwiritsa ntchito zosiyanasiyana kuchokera ku 0 V mpaka VREF. Buku lotchedwa voltage setting liri losiyana ndi mphamvu ya analog (AVDD) ndipo ndi apamwamba kuposa AVDD. Kutembenuka kumeneku kumapezeka kudzera njira yosavuta yogwiritsa ntchito SPI yokhala ndi mawonekedwe atatu a waya. Zida zimenezi zimakhala ndi 1 M sampuli / yachiwiri, njira imodzi yolowera, mphamvu yamagetsi (0.8 & micro; A choyimira, 1.6 mA yogwira ntchito), ndipo amaperekedwa mu phukusi la MSOP la 10-pin. ADCs MCP331 imapereka zosiyana zowonjezera, zopindulitsa kwambiri, ndi kugwiritsira ntchito mphamvu zochepa mu phukusi laling'ono. Maonekedwe olemerawa amapangitsa kuti izi zikhale zoyenera kwa machitidwe opangira ma batri komanso mafomu omwe akupezeka kuti akugwiritsanso ntchito ngati mankhwala, magalimoto, magetsi, ndi magetsi.

- Sewero la SCLK maola: mpaka 100 MHz
- ADC kudzidzimadzira payekha zolakwika, zopindulitsa, ndi zofanana:
- Pogwiritsa ntchito mphamvu
- Kufunidwa kudzera pamsinkhu & rsquo; s ndikugwira ntchito nthawi zonse
- AEC-Q100 oyenerera:
- Kutentha kolasi 1: -40 & deg; C mpaka 125 & deg; C
- Kupeza deta kwambiri
- Zida zamankhwala
- Zida zoyesa
- Machitidwe oyendetsa galimoto zamagetsi
- Kugwiritsa ntchito magalimoto
- Sinthani machitidwe ogwiritsira ntchito mphamvu
- Zida zamagetsi
