Hi TI's ananlog expert, We are using the TX_SDK_V1 evaluation board. We found that when we turn on the LM96530 receiving channel, the output of the LM96530 will have a DC bias which will add low...

Hi, Usually, the output of the LM96530 is AC coupled to the receiver. Or you can put a 50 Ohm resistor from the output to ground. Regads, Charles

Hi, Thank you for your reply. We use the AFE5803EVM to receive the output of the TX_SDK_V1. So the output of the LM96530 is AC coupled to the receiver. LM96530 OUTPUT AFE5803 INPUT Later we change the...

Hi, Can you double check that the LM96530 is turn on by looking at the supply current for the LM96530 ? Regards, Charles

Hi, Charles, Thanks for your reply. I am sure the LM96530 is turned on for the +-5V power supply's current is 0.075mA and dropped to 0 when turn off the 8 channel of the LM96530 . Besides, only turn on...

Hi folks, It seems tha the TSC 2004 hangs after following power sequence. In this case, the TSC2004 would not send ack and also never output xPINTDAV. Also the xRESET is NOT effective for recovering...

Hi Phx, I think you mean 75mA right? How about changing the 2.5KOhm output resistor (from output to ground) to 500 Ohm and/or increase the Rref resistor by redcucing the Icc? Looks like the offset is...

Hello Adam Garrison1, The output will be turned off when the over current limit is reached as shown in the “CURRENT LIMIT SHUTDOWN WAVEFORMS” (pag. 5 of the DRV104 datasheet). If the power dissipation...

Hi Charles, Thanks for your help. Sorry, I made a mistake. The the +-5V power supply's current is 0.075A and dropped to 0.013A when increase the Rref resistor from (RREF = 6.25 kΩ → IS = 8mA) to (RREF...

Hi Phx, What signal is at the input of LM96530 ? It's around 100KHz too? If it's, there would be capacitive coupling from the input. Regards, Charles

Hi Charles, The jumper between the LM96551 and LM96530 is taken away. So there is no input signal of LM96530 . Later we found that when all power off except VSUB, the low frequency noise still exist....
