在集成电路中，通常采用T型解码网络实现数字量往模拟的转换，再利用运算放大器完成模拟电流变为模拟电压的转换。所以，要把一个数字量变为模拟电压，实际上需要两个环节，先把数字量变为模拟电流，这是由D/A转换器完成的；再将模拟电流变成模拟电压，这是由运算放大器完成的。有时D/A转换器芯片只包含前一个环节，有些D/A转换器则包含两个环节，用前一种芯片时，需要外接运算放大器才能得到模拟电压。-In integrated circuits, the usual T-decode digital networks to analog conversion, and then complete the simulation of the use of op-amp current into the analog voltage conversion. Therefore, it is necessary to become a digital simulation of voltage, in fact, need two links, first into a digital simulation of currents, this is determined by D/A converters completed then simulate current into the analog voltage, this is determined by computing completed amplifier. Sometimes D/A converter chip contains only a part before, some D/A converter includes two aspects, before a chip, the need for external op-amp voltage can be simulated.

用单片机芯片ht46rb50温度计的设计、广告等。ht46rb50
本次设计的温度计采用HT46RB50 微控制器IC，HT46RB50 的AD 口外接一热敏电阻，通过
AD 读回的电压计算出热敏电阻阻值的变化，从而实现侦测外界温度的功能。HT46RB50 通
过USB 将侦测到的温度值传入PC 机的温度显示接口中显示。
本次设计的USB 使用操作系统提供的USB HID 设备类驱动程序。
• 采用USB 控制传输向HT46RB50 发送资料
• 采用USB 中断传输接收HT46RB50 传回的资料-The design of the thermometer used HT46RB50 microcontroller IC, HT46RB50 of AD external mouth of a thermistor, through the AD read-back voltage to calculate the changes in thermistor resistance in order to achieve the function to detect the outside temperature. HT46RB50 through the USB will be detected by the temperature of the temperature of incoming PC-display interface to display. The USB to use the operating system designed to provide the USB HID device class driver.
