Forum Post: RE: RE: ADS1118 CS and SCLK Crosstalk
Hi Shravan,If you are seeing a lot of digital crosstalk, you probably are seeing a grounding problem. If you are not using a PCB, but rather a prototyping system such as solderless breadboard, then...
View ArticleForum Post: RE: TLV320AIC1110 so much noise
Please check the power supply. How does your /AUDIO_ON switch work? If /AUDIO_ON is 0V, VT32 is off and the gate of VT31 is 3.3V through R123 so VT31 is off too therefore the AIC1110 is not powered.If...

Hi Sunny,I'm afraid I don't follow.C = 1000pF and for no object near, L = 640.5uH and Rs = 222ohm ...Rp = L/(Rs*C) = 2.89k ohmf = 191 kHzAre these outside the allowed range for the LDC1000?
