Pulse Staircase Ramp Generator
This design highlights the use of the LTC6993-2 and LT1490 to generate a pulse staircase ramp that is re-triggerable. The pulse staircase ramp output is generated by the LT1490 dual op amp converts pulse frequency-to-voltage and generates a staircase output. The LTC6993-2 is then configured to reset the staircase.The LTC6993-2 is a one-shot pulse generator with a programmable pulse width that can be re-triggered.
