Description

PCF8591 AD/DA晶片介紹

PCF8591是一個單片集成、單獨供電、低功耗、8-bit CMOS資料獲取器件。PCF8591具有4個模擬輸入、1個類比輸出和1個串列I2C匯流排界面。PCF8591的3個地址引腳A0, A1和A2可用於硬體位址程式設計,允許在同個I2C匯流排上接入8個PCF8591器件,而無需額外的硬體。在PCF8591器件上輸入輸出的位址、控制和資料信號都是通過雙線雙向I2C匯流排以串列的方式進行傳輸。

PCF8591 主要性能指標:

★單電源供電

★PCF8591的操作電壓範圍2.5V-6V

★低待機電流

★通過I2C匯流排串列輸入/輸出

★PCF8591通過3個硬體位址引腳定址

★PCF8591的取樣速率由I2C匯流排速率決定

★4個模擬輸入可程式設計為單端型或差分輸入

★自動增量頻道選擇

★PCF8591的類比電壓範圍從VSS到VDD

★PCF8591內置跟蹤保持電路

★8-bit逐次逼近A/D轉換器

★通過1路模擬輸出實現DAC增益


二 寶貝描述

1 模組晶片採用PCF8951

2 模組支援外部4路電壓輸入採集(電壓輸入範圍0-5v)

3 模組集成光敏電阻,可以通過AD採集環境光強精確數值

4 模組集成熱敏電阻,可以通過AD採集環境溫度精確數值

5 模組集成1路0-5V電壓輸入採集(通過藍色電位器調節輸入電壓)

6 模組帶電源指示燈(對模組供電後指示燈會亮)

7 模組帶DA輸出指示燈,當模組DA輸出介面電壓達到一定值,會點亮板上DA輸出指示燈,電壓越大,指示燈亮度越明顯;

8 模組PCB尺寸:3.6cm*2.3cm

9 標準雙面板,板厚1.6mm ,佈局美觀大方,四周設有通孔,孔徑為:3mm,方便固定
