DAC43902-Q1: How to Generate PWM O/P and Vary the PWM Frequency and Duty cycle with DAC43902-Q1

Mukesh k

Part Number: DAC43902-Q1

Hi Team,

We're trying understand how to generate PWM signals from DAC43902-Q1.

Also, how to vary the frequency and duty cycle in standalone.

As per my understanding in standalone mode I2C interface won't work. Then, how we will control frequency and duty cycle.

Our Requirement,

2 PWM outputs with individual controls (variable frequency and duty cycle)

Hi Mukesh,

The DAC43902 cannot be controlled with the I2C interface. This device is for fade-in fade-out applications and it has an input trigger to start/stop the fade. I will respond in your other open forum post.

Best,

Katlynne Jones
