MAX038 DIY Function Generator Kit

Build a function generator and explore how circuits respond to different waveforms. This MAX038-based DIY kit provides the components for a bench signal source, with frequency, amplitude and offset adjustment in the completed circuit.

✅ Try different input waveforms - The completed circuit provides sine, rectangular, triangle and sawtooth outputs.

✅ Change more than the frequency - Amplitude, duty-cycle and DC-offset controls support different compatible tests.

✅ Include a timing reference - A SYNC output provides a signal for a suitable measurement arrangement.

Build the Circuit Before Using the Signal

A signal-generator project can teach the relationship between a selected waveform and the response of a circuit under test. Building the source adds another learning stage before you connect it to the rest of the bench.

This is a DIY kit, not a ready-to-use assembled instrument. Follow the assembly and checking procedure, then verify the output with appropriate equipment before applying it to another circuit. Match the signal level and offset to the receiving circuit's limits.
