Schematica Software

A free software calculator that features a 555 timer with three astable modes and one monostable mode. Resistor and capacitor values can be adjusted, and astable modes include duty cycles of 50% and above, as well as below 50%, for maximum customization.

This software designs lowpass, highpass, bandpass, and bandstop filters for electronics using resistors, capacitors, and op amps. It offers a range of circuit options and approximations up to order 10 for Butterworth, Chebyshev, Elliptic, and Bessel filters.

This software can identify resistor values from color bands or SMD markings for both 4 and 5 band leaded-type resistors, as well as 3 and 4 digit Surface Mount Device codes. It can also determine EIA-96 1% SMD codes and 2, 5, 10% SMD codes.

555 Timer PRO offers design tools, circuit modules, and information panels to simplify the use of 555 timer. The software calculates component values based on the timer's fabrication and supply voltage, whether it is CMOS or Bipolar.

This software allows for the design of various electronic filters using resistors, capacitors, and op amps. It offers Butterworth, Chebyshev, Elliptic, and Bessel approximations up to order 20, with lowpass, highpass, bandpass, and bandstop settings, and provides multiple circuit options.

This electronic circuit simulator provides fast schematic capture and a range of simulation features such as Monte Carlo analysis, Parameter Sweep analysis, and Pole-Zero calculation. It also includes multiple voltage probes, input impedance, and both real and ideal op amp models.
