TLC2543是德州仪器公司生产的12位开关电容型逐次逼近模数转换器，它具有三个控制输入端，采用简单的3线SPI串行接口可方便地与微机进行连接，是12位数据采集系统的最佳选择器件之一。这是我电子设计大赛是用的，希望采纳。-Is produced by Texas Instruments TLC2543 12 switched capacitor successive approximation ADC, which has three control inputs, a simple 3-wire SPI serial interface can be easily connected with the computer is a 12-bit data acquisition system one of the best choice for the device. This is my Electronic Design Contest is used, hope to adopt.
