有更好用的器件啊
比如TMP35等,給個5V電源,它在25度時輸出250MV,75度時輸出750MV,特別適合用于檢測溫度.大小和三極管一樣,
當然價格比二極管高多了.

謝謝回復.不知這個多少錢啊.
它的DATSHEET上給的溫度曲線是VIN=3.3V的,不知5V時,輸出電壓是多少?

謝了,這個多少錢一只?
DATASHEET上未給出5V時的電壓輸出的曲線,不知100度時,輸出多少V

多少錢?
11

價格
力源的公開報價是八塊多,別的地方批量能五塊錢拿到吧.

工作電壓范圍2.7到5.5V
輸出電壓只跟隨溫度都一樣

why not use the ICs with built in over temperature protection function. It seems the price is little bit high, but the system cost is much lower since the componenet you guys are talking about is much more than the IC itself. Why do you save 1 cent on the IC and spend 1 dollar on the compoenets to design for the function the other ICs alraedy built in?
Any comments are welcame.
