I have a DAC design with TLV5613CPW. THe requirement of my system, I need to generate analog data at the rate of 1Msps minimum, prefer 2Msps. The purpose of my DAC is to generate a waveform as in the image attached here. The data I send to the DAC can be like this code below:
unsigned int data_dac;
But there is the problemin my design: Each time I update the DAC value, there is an over/under shoot as in the image her. If you know why I have this problem and you know how I can solve this problem, please help.
For your infor, I drive the DAC with PIC18F26J50-I/SS.
I only want to get help from experience electrical engineer, with very strong Analog back ground, and you had done semilar design like mine. Will not accept any paid up front. And I will pay you in full if when your help really improve my design.
