The question that arises in the design of a simple PWM DAC is what the low-pass filter pole frequency should be relative to the PWM frequency. This question is addressed by deriving the design ...

You can generate a variable dc reference voltage with a DAC or with a PWM (pulse-width-modulation) signal from your controller (Figure 1). The accuracy of the voltage source that the ...

Pulse-width modulation (PWM) peripherals have enjoyed a long association with microcontrollers and power control, starting with motor control and power conversion. For the most part, these ...

Sometimes a design need more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a pulse-width modulator (PWM) circuit and filter it output with an RC filter. An ...

mCODa-MT1-LR.01 is an audio CODEC which provides the insurance of the best sound quality after integration into a SoC for IP Camera or Car dash Camera applications. It benefits from unique features, ...
