产品概览
MAX6682MUA+T from ADI/Maxim is a remote-junction temperature sensor with SPI interface. +/-1C accuracy. Measures external P-N junction (transistor/diode). MU-8 (MSOP-8).
工作原理
Measures temperature of external P-N junction (2N3906-type transistor or diode). Two measurement currents ratio-metrically determine junction forward voltage, which is proportional to temperature. SPI output 12-bit result.
