摘　　要：在使用6MHz或12MHz晶振频率的MCS-51系统中,测试DAC0832电路的数模转换速度和可靠的操作频率.实验结果表明:数字量的切换幅度是影响数模转换速度的主要因素,较为可靠的最高数模转换的操作频率不超过30kHz.本实验为在工程应用中合理和高效操作DAC0832数模转换电路提供了可靠的参考依据.In the mcs51 system used 6 or 12 MHz oscillation frequencies, to measure the digital to analog converting speed and reliable operating frequency of the DAC0832 circuit. The measured results showed that converting speed of DAC0832 circuit is obvious affected by the digits converting extent; the reliable operating frequency doesn't surpass 30 kHz. The measured results supply reliable reference basis for reasonable and efficient operating DAC0832 circuit in projects application.
