MAX31889 ± 0.25 ° C Molondola I2C Kutentha SENSOR

Maxim Integrated's MAX31889 high-precision I2C sensor ya kutentha pa bajeti yamagetsi yamagetsi

Maxim Integrated's MAX31889 ±0.25°C Accurate I2C Temperature Sensor Maxim Integrated's MAX31889 ndimphamvu yamagetsi yotsika kwambiri, yolondola kwambiri ya digito yokhala ndi ± 0.25 ° C molondola kuchokera -20 ° C mpaka + 105 ° C ndi ± 0.65 ° C molondola kuchokera -40 ° C mpaka + 125 ° C omwe amagwira ntchito kuchokera 1.7 V mpaka 3.6 V magetsi. MAX31889 ili ndi malingaliro a 16-bit (0.005 ° C).

Chipangizocho chimagwiritsa ntchito standard I²C chosanjikiza cholumikizira wolamulira. Zipini ziwiri za GPIO zilipo. GPIO1 ikhoza kukhazikitsidwa kuti ipangitse kutembenuka kwa kutentha pomwe GPIO0 imatha kukhazikitsidwa kuti ipangitse kusokoneza mabatani osankhidwa.

MAX31889 imaphatikizira 32-mawu FIFO pazosinthira kutentha ndikuphatikizanso ma alarm a kutentha kwapamwamba komanso kutsika. Chipangizocho chimapezeka mu 2 mm x 2 mm x 0.8 mm, pini 6, phukusi la µDFN.
