For not using a scope, this method is pretty accurate, and only uses two discrete circuit components (the resistor and the speaker). If you’re ever in a pinch with PWM, this is sure to help ...

In addition to these PWM modes there is also a "Low Ripple DAC" mode that creates a minimum period pulse train whose High/Low average is that of the chosen duty cycle. When used with a low-pass filter ...

Description: -delta converters, such as non-linear inter symbol interference (ISI) and kickback noise on the reference of the DAC. This silicon-proven IP block implements a digital PWM sigma-delta ...

We've learned many techniques for switching DC circuits; high side switching, low side switching, motor drivers and PWM circuits to mention a few. We even briefly looked at switching low voltage, low ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed ...
