Note 1: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JED
EC J-STD-020C for MSL classification at lead-free peak reflow temperature. ANPEC defines
“Green”
to mean lead-free (RoHS
compliant) and halogen free (Br or Cl does not exceed 900ppm by weight inhomogeneous material and total of Br and Cl does not
exceed 1500ppm by weight).
ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and
advise customers to obtain the latest version of relevant information to verify before placing orders.

一个关于DSP28335的ADC模块采集电压问题
       各位大佬,我想请教两个问题。他困扰了我一个下午,不胜感激!!!       问题1:我使用TI公司TMS320F28335配置4路ADC通道,没有接入外部电压但是已经有1V电压值值。非常奇怪?       问题2:我只把一路(A0)和模拟地短接,为什么会影响(A1)通道电压值。通过watchwindow观测变量值,A0为0,A1为518。      ADC模块配置代

【转帖】测定晶体振荡器质的小窍门
测量晶振好坏 ,时常让初学者头大。偏偏晶振的体积非常小,但是在主板上起的作用却很大,因此晶振的检测是主板维修非常重要的环节。如何快速简单的判断检测晶振的好坏呢? 1.用万用表(R×10k挡)测晶振两端的电阻值,若为无穷大,说明晶振无短路或漏电;再将试电笔插入市电插孔内,用手指捏住晶振的任一引脚,将另一引脚碰触试电笔顶端的金属部分,若试电笔氖泡发红,说明晶振是好的;若氖泡不亮,则说明晶振损坏。2.
