What's the simplest (smallest footprint) way to generate a PWM signal from an analog signal?
I have a circuit that works fine with a 555 and a comparator. However, I need absolutely minimal footprint, and there must be small, dedicated chips out there.
The analog input is 1~4V. The output is approx 50kHz. Preferably the duty cycle goes from 0% to 100%.
