Hello,
I'm using the DAC63204EVM with your GUI.
I'm trying to generate a PWM signal. I connected the FB pin to a voltage divider to create VFB=0.5VDD and define the output as a triangle wave
.I've set MH and ML values.
However, when I attempt to adjust the SLEW RATE and CODE STEP, I don't see any response on my oscilloscope.
I'm trying to generate the signal at different frequencies around few KHz (3KHz- 7KHz).
According to the datasheet, I need control over the SLEW RATE to define different frequencies.
Can I achieve this frequency with this DAC?
See My calc below. am I using the formulas correctly?
| Parameter | Value | Unit |
| VDD | 5 | V |
| R1 | 1 | Kohm |
| R2 | 1 | Kohm |
| Vfb | 2.5 | V |
| MarginHVoltage | 3 | V |
| MarginLVoltage | 2 | V |
| SlewRate | 4.00E-06 | sec/step |
| MarginH | 2458 | |
| MarginL | 1638 | |
| CodeStep | 32 | LSB |
| f | 4.88E+03 | Hz |
| Duty Cycle | 50.000 | % |
Thanks,
