| Abstract: | A design method of 13 bit D/A converter resolution is introduced by using 12 bit dual D/A con- verter TLC5618. The hardware interface circuit between the TLC5618 and the microcontroller AT89C55 and the realization principle of hardware for 13 bit D/A converter resolution are presented, and the correla- tive function programs compiled with C51 are given. This method has a1ready been applied to the design of the smart instruments and PLC module. |
