Other Parts Discussed in Thread: MSP430FR5969
Hi,
I am using the MSP430FR5969 to output a PWM to drive a gate for a current source as seen in the attached file. I am hoping my DC voltage accuracy to be 1% after the low pass filter.
I plan on using setting SMCLK = MCLK = DCO to 16 MHz and having ACLK = 32678Hz. How will changing my pwm frequency impact my DC voltage accuracy? How do I calculate the error and resolution in respect to my clocking and timing?
I also plan on using an LDO to supply the MSP430 (1.15% at 25°C). Will the 1.15% deviation from the supply also impact the amplitude of the PWM? Would the error be 1.15% as well?
