Hi Joel. Sorry for late response. We use 1uF ceramic capacitors, as recommended in the datasheet. I check the voltage with oscilloscope and it looks OK for me. 3.3V digital, this voltage is more rush, but in range of +-40mV 3V analog. This voltage is regulated from the 3.3V digital and is much smoother. Sometimes there are the peaks of +-20mV with length of around 150us, which I don't think should be a problem. Also I don't think that the BOR really occurs, because otherwise I wouldn't be able to measure any RMS at all... Also the problem with clearing the bit in STATUS register I have also with the RMS_DONE bit. This is I2C capture for BOR bit clear:
