DIGITAL-ANALOG CONVERTER TEST DEVICE

摘要

PURPOSE: A digital-analog converter test device is provided to enhance easily the resolution of a test device and upgrade it with ease by improving the sampling speed of an analog-digital converter. CONSTITUTION: The digital-analog converter test device comprises; a clock pulse generating part(10) to generate the 1st clock pulse(DA-CLK) and the 2nd clock pulse of which cycle is 1/n of that of the 1st clock pulse(AD CLK); a digital-analog converting part(20) to convert inputted N bit digital words into analog signals in response to the 1st clock pulse(DA CLK); an analog-digital converting part(40) to output N+2 bit digital words by digital converting the analog signal provided from the digital-analog converting part(10) by the 2nd clock pulse(AD CLK) cycle.
