3 說明
LDC1101 是一款 1.8V 至 3.3V、高分辨率電感數(shù)字轉(zhuǎn)換器，可對(duì)位置、旋轉(zhuǎn)或運(yùn)動(dòng)進(jìn)行短距離、高速、無觸點(diǎn)感測，即使存在污垢或灰塵也能夠?qū)崿F(xiàn)可靠、精確的測量，非常適合戶外或嚴(yán)苛環(huán)境。
LDC1101 特有雙感應(yīng)測量內(nèi)核，可在執(zhí)行 > 150ksps 的 16 位 RP 和 L 測量的同時(shí)，進(jìn)行分辨率高達(dá) 24 位的高分辨率 L 測量，采樣速率可高達(dá) 180ksps 以上。 LDC1101 包含閾值比較功能，該功能可在器件運(yùn)行時(shí)動(dòng)態(tài)更新。
電感感測技術(shù)可實(shí)現(xiàn)對(duì)線性/角位置、位移、運(yùn)動(dòng)、壓縮、振動(dòng)、金屬成分以及市面上包括汽車、消費(fèi)類、計(jì)算機(jī)、工業(yè)、醫(yī)療和通信應(yīng)用在內(nèi)的很多其他應(yīng)用的高精度測量。 電感感測技術(shù)能夠以低于其他競爭對(duì)手解決方案的成本提供更為出色的性能和可靠性。
LDC1101 在小型 3mm × 3mm 10 引腳 VSON 封裝內(nèi)即可提供這些電感感測技術(shù)優(yōu)勢。 微控制器可使用 4 引腳 SPI™輕松配置 LDC1101。
