As a mobile multi-purpose platform, tablet computers also provide many possibilities for mobile teaching. The touch-based learning & entertainment teaching platform allows children to efficiently improve their academic performance in a relaxed and pleasant atmosphere. Such tablet computers generally integrate two learning sections of various courses and systematic learning functions. Generally, it includes multi-disciplinary high-quality teaching resources. The education tablet has the following main functions: it has the functions of touch screen input, text editing, picture editing, data storage, data management, wired and wireless Internet access that ordinary tablet computers have; Management functions, search methods support manual search, query by keyword, query by time; text and pictures can be scanned and converted into documents to save.

The impact on the design was checked. 6 Do not use frequency on the unit gain bandwidth. 7 Check the stability of the capacitive load 8 If there is a capacitor between the negative and positive inputs, stability analysis must be performed. 9 The common mode input voltage range of the op amp is respected. 10 At the input, all comparator components are safe (low or high during abnormal voltages). Maximum current, maximum power, maximum energy, and maximum voltage do not damage components. 11 In the abnormal voltage (low or high) of the input signal, the comparator output signal must be considered undefined 12 At the IC pin level, the two equivalent dc inputs have impedances in the same range.
