LM75 / LM75A Digital Temperature Sensor — I²C Interface

Ang LM75A ay isang digital temperature sensor na idinisenyo para sa tumpak na pagsukat ng temperatura sa malawak na operating range. Sinusukat nito ang mga temperatura mula -55 °C hanggang +125 °C at nakikipag-ugnayan sa isang host controller sa pamamagitan ng isang high-speed I²C interface, na nagbibigay-daan para sa mabilis at madaling pag-integrate sa system.

Sa suporta para sa parehong I²C at SMBus interfaces, ang LM75A ay nagbibigay ng mga flexible na opsyon sa koneksyon. Tatlong mapipiling logic address pins ang nagpapahintulot sa maraming device na magbahagi ng parehong bus nang walang mga conflict sa address, na ginagawa itong angkop para sa mga disenyo na may maraming sensor. Ang kombinasyon nito ng precision, configurability, at mababang power operation ay ginagawa itong angkop para sa mga aplikasyon ng temperature monitoring, thermal management, at temperature control.


Mga Pangunahing Tampok

  • Expandable I²C slave address (1001xxx)
    Sumusuporta hanggang walong device sa parehong bus

  • Malawak na operating ranges

    • Supply voltage: 2.8 V hanggang 5.5 V

    • Temperature range: -55 °C hanggang +125 °C

  • 11-bit ADC

    • Temperature resolution: 0.125 °C

    • Accuracy: ±2 °C

  • Programmable temperature limits
    Naaayos na mga set point para sa temperature threshold at hysteresis

  • Low power sleep mode
    Ang kasalukuyang konsumo ay kasingbaba ng 1.0 µA

  • Standalone operation
    Maaaring gamitin bilang isang stand-alone temperature controller
