Hello,

Regarding the flicker, you know this and I know this, however, we are trying to match an existing product that is set at 25khz. It appears at lower frequencies
it is causing their power supply to make audible noise at the PWM frequency. And sure enough, at 1khz, at certain pwm levels, we can hear it in the power supply. I don't have to keep the oscillator at 4khz, but I assume making any changes to the main Oscillator will also affect the touch circuit, as well. I did see in the pwm section of the datasheet that the resolution drops depending on the oscillator frequency after I posted this. Thanks again!
