    產(chǎn)品信息

    The ADM1023 is a 2-channel digital thermometer and under- and overtemperature alarm for use in personal computers and other systems requiring thermal monitoring and management. Optimized for the Pentium? III, the higher accuracy allows systems designers to safely reduce temperature guard banding and increase system performance. The device can measure the temperature of a microprocessor using a diode-connected PNP transistor, which may be provided on-chip with the Pentium III or similar processors; or it can be a low-cost, discrete NPN/PNP device such as the 2N3904/2N3906. A novel measurement technique cancels out the absolute value of the transistor's base emitter voltage so that no calibration is required. The second measurement channel measures the output of an on-chip temperature sensor to monitor the temperature of the device and its environment.
    • On-chip and remote temperature sensing
    • Offset registers for system calibration
    • 1°C accuracy and resolution on local channel
    • 0.125°C resolution/1°C accuracy on remote channel
    • Programmable over/under temperature limits
    • Programmable over/under temperature limits
    • 2-wire SMBus serial interface
    • 200 μA max operating current (0.25 conversions/second)
    • 1 μA standby current
    • 3 V to 5.5 V supply

    ADM1023ARQZ-REELONADM1023 是一款兩溝道數(shù)字溫度計和溫度過低/過高報警器，適用于需要熱監(jiān)控和熱管理的個人電腦和其他系統(tǒng)。該器件提供的更高準確度針對 Pentium III 而優(yōu)化，讓系統(tǒng)設(shè)計人員能夠安全降低溫度保護帶，提高系統(tǒng)性能。該器件可以使用 Pentium III 或類似處理器片上附帶的二極管聯(lián)接 PNP 晶體管測量微處理器的溫度；也可以是低成本的分立 NPN/PNP 器件，如 2N3904/2N3906。新型測量技術(shù)消除了晶體管基極-射極電壓的絕對值，因此不需要校準。第二個測量溝道測量片上溫度傳感器的輸出以監(jiān)測該器件及其環(huán)境的溫度。 立即購買
