There is error in the data sheet. The figure and application note is correct, section 5-2 in the data sheet is incorrect.
The correct device code is 1001

各位大大 , microchip的類比元件板怎麼如此冷清.....
我近來用了一顆外部的12bit ADC , SOT23包裝 , 做KEY PAD用 , PIC不用選的太大顆來做KEY SCAN , 也不用ADC INT.所以便宜的PIC+便宜又小的ADC , 解決了長期困擾的問題 , 因為主管一直在砍我設計的板子大小 , 已經塞到ANTS都快走不過了還要縮 , 很難很難 , 剛好找到這一個 , 下個CASE拿來做電池低電量偵測 , 不知道夠不夠用?試試看就知道了 , 在這裡推蔫給受到產品體積大小所困擾的RD同好們參考 , 板主 , 請問一個問題, 在I2C的位址設定上 , 時序圖中畫的是1001 , 但說明中寫的1010 , 我好像是用1001才讀到資料 , 那個才是對的?
