描述 Description

HAL 880滿足現(xiàn)今高質(zhì)量線性和角度測(cè)量應(yīng)用的要求，并具有補(bǔ)償系統(tǒng)誤差的靈活性。由于其可編程，產(chǎn)品提供了可以補(bǔ)償系統(tǒng)誤差的額外優(yōu)勢(shì)。這對(duì)于油門踏板、電流測(cè)量，方向燈或大燈調(diào)節(jié)等應(yīng)用是必須的。產(chǎn)品帶有實(shí)現(xiàn)的斷線探測(cè)，和拉起火拉下式電阻一起工作，提供線性或者比例模擬輸出信號(hào)。諸如磁場(chǎng)范圍，敏感度，VOQ（零磁場(chǎng)下輸出電壓）和溫度系數(shù)等主要特性可以在非易失性內(nèi)存中通過對(duì)磁電路（線性和角度）編程來輕易調(diào)節(jié)。HAL880有含鉛的 TO92UT封裝或者SMD SOIC8封裝。
