摘　　要：为保证高精度数模转换器的性能,在设计和使用高精度DAC的外围接口电路时应考虑到数据输入、基准电压、输出驱动、电源管理、数字时序逻辑等因素,只有严格设计才能保证DAC的正常使用,并减小外围接口电路带来的失调误差、增影院差等。In order to ensure the performance of high - accuracy Digital - to - Analog Converter, we must consider some kinds of factors in designing and application, such as data input, reference voltage, output buffer, power - supply management, digital logic. Through the careful design, the high - accuracy DAC system will work well and reduce to the lowest errors which come from the external interface.
