... The simplest and most accurate method to program the LTC6994 is to use a single resistor, R and GND pins. The design procedure is a 3-step process. Alternatively, Linear Technology offers the easy-to-use TimerBlox Designer tool to quickly design any LTC6994 based circuit. Download the free TimerBlox Designer software at www ...
