2024: A year’s worth of interconnected themes galore
As any of you who’ve already seen my precursor “2025 Look Ahead” piece may remember, we’ve intentionally flipped the ordering of my two end-of-year writeups once again this year. This time, I’ll be looking back over 2024: for historical…
PWM power DAC incorporates an LM317
Instead of the conventional approach of backing up a DAC with an amplifier to boost output, this design idea charts a less traveled by path to power. It integrates an LM317 positive regulator with a simple 8-bit PWM DAC topology to obtain a…
