24-bit PWM Pulse Width Modulation DAC (Part 3)
As shown in the figure below, the FLUKE5700 uses a patented26bit DAC, which serves as a programmable voltage divider. This DAC is of the pulse width modulation (PWM) type, with linearity better than 1 ppm (parts per million) across the range from one-tenth scale to full scale. The DAC output voltage is represented in software … Read more
