Figure 1 Circuit schematic of triangle/sawtooth wave generator using 555 timer. Assuming that the circuit has reached steady-state, then the working principle is as follows: When the voltage across ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

555 Timer Alternative A smart DAC also can serve as an alternative to the venerable 555 timer (Fig. 3), which engineers have used for years to solve a variety of system design problems.
