Multichannel Remote/Local Temperature Sensors

General Description The MAX1668/MAX1805/MAX1989 are precise multichannel digital thermometers that report the temperature of all remote sensors and their own packages. The remote sensors are diode-connected transistors—typically low-cost, easily mounted 2N3904 NPN types—that replace conventional

多通道遠(yuǎn)端/本地溫度傳感器

MAX1668/MAX1805/MAX1989均為高精度多通道數(shù)字溫度計(jì)，可報(bào)告所有遠(yuǎn)程傳感器及其自身封裝的溫度。遠(yuǎn)程傳感器為二極管連接式晶體管（通常為低成本、易于安裝的2N3904 NPN型），可取代傳統(tǒng)的熱敏電阻或熱電偶。對(duì)于多個(gè)晶體管制造商來(lái)說(shuō)，遠(yuǎn)程精度為±3°C，無(wú)需校準(zhǔn)。遠(yuǎn)程通道還可以測(cè)量其他包含片上二極管連接式晶體管的IC（例如微處理器）的芯片溫度。\n\n 2線(xiàn)串行接口接受標(biāo)準(zhǔn)系統(tǒng)管理總線(xiàn)(SMBus?)寫(xiě)入字節(jié)、讀取字節(jié)、發(fā)送字節(jié)和接收字節(jié)命令，以對(duì)報(bào)警閾值進(jìn)行編程并讀取溫度數(shù)據(jù)。數(shù)據(jù)格式為7位加符號(hào)，每一位對(duì)應(yīng)1°C，采用二進(jìn)制補(bǔ)碼格式。\n\n MAX1 ? 多通道\n? 4個(gè)遠(yuǎn)程通道，1個(gè)本地通道(MAX1668/MAX1989)\n\n? 2個(gè)遠(yuǎn)程通道，1個(gè)本地通道(MAX1805)\n\n\n\n\n? 無(wú)需校準(zhǔn)\n\n?
