Q. LT1328, There is no Tx signal, but there is an Rx signal.

Hello.

I received the following guide through EZ.

{

The LT1328 has high and varying sensitivity.  Sometimes the sensitivity is so high that thermal noise triggers its input beyond the offset, causing spurious output response.

To reduce the sensitivity, apply a 3Meg pullup resistor from the Bias pin to 5V.

}

As a result of tuning the pull-up resistor, it was resolved at 470kohm.

There is a difference in the value of the pull-up resistor, is it okay?

Please check quickly.

Thanks,

Leo
