Designing a very simple I2C bus with one master and one slave. The slave datasheet states a pull up of 1.5k or greater whereas the master datasheet specifies a 33k. I am concerned about using a 33k, I wanted something closer to 2. I understand that really this is just an RC constant. As R increases the time constant will increase, therefore the rise time will increase, therefore the bus speed will decrease. As a designer how would you approach this problem?

For more context, the master is a BT/Audio chip that is driving a class D amplifier for driving a speaker. The i2c bus in this case sets the register settings on the amp and these settings are adjusted in response to the voltage and current sense feedback coming from the class D.

Hey yall,

I am so done with google from the worsening results to their trash AI to them harvesting any information they can out of me. what are your preferred alternatives? I am assuming a lot of you use a combination of different search engines?

I’m wondering is Cardio Vascular surgeons get irritated and depressed at their obese patients. Imagine treating your body so poorly that you have to get sliced open. I’m assuming a huge percentage of CV surgeon patients are obese and their medical issues were completely preventable. This, as a surgeon would frustrate me and make me very depressed.
