AD7543的逻辑电路由12位串行输入并行输出移位寄存器(A)和12位DAC输入寄存器(B)以及12位DAC单元组成。在选通输入信号的前沿或后沿(由用户选择)定时地把RSI引脚上的串行数据装入寄存器A，一旦寄存器A装满，在加载脉冲的控制下，寄存器A的数据便装入寄存器B。并进行D/A转换。-将中文译成英语显示罗马拼音



AD7543 12-bit logic circuit from the serial input parallel output shift register (A) and 12-bit DAC input register (B) and 12-bit DAC modules. Strobe input signal in the front or back along the (user selected) time in the RSI pin on the serial data into register A, if register A full, under the control of the loading pulse, the data register A casual into the register B. And for D/A converter.
