數(shù)據(jù)： TMP275 具有 I2C 和 SMBus 接口的 ±0.5°C 溫度傳感器（采用行業(yè)標準 LM75 尺寸和引腳） 數(shù)據(jù)表 (Rev. E)
TMP275是一款精度為±0.5°C且具有12位模數(shù)轉(zhuǎn)換器（ADC）的集成數(shù)字溫度傳感器，可在低至2.7 V的電源供電下運行，并且與德州儀器（TI）的LM75，TMP75，TMP75B和TMP175引腳和寄存器兼容。此器件采用SOIC-8和VSSOP-8兩種封裝，不需要外部組件便可測溫.TMP275能夠以最高0.0625°C（12位），最低0.5°C（9位）的分辨率讀取溫度，從而允許用戶編程更高的分辨率或更短的轉(zhuǎn)換時間來最大限度地提升效率。此器件的額定工作溫度范圍為-40°C至125°C。
TMP275器件特有系統(tǒng)管理總線（SMBus）和兩線制接口兼容性，并且可在同一總線上，借助SMBus過熱報警功能支持多達8個器件。廠家校準的溫度精度和抗擾數(shù)字接口使得TMP275成為其他傳感器和電子元器件溫度補償?shù)氖走x解決方案，而且無需針對分布式溫度感測進行額外的系統(tǒng)級校準或復雜的電路板布局布線。
