Hi,
We are using OPA2836 ICs on our board to support P and N lines for a differential pair. On the board after there are two paths TX and RX and at end of TX path and starting of RX path this IC is used in unity gain configuration. it has output pin shorted to negative input pin. when we do a loop back i.e. connect the output from IC in TX directly to positive input pin of other IC in RX path the output of TX Op-amps start oscillating. and the oscillation is same in amplitude as well as frequency for both P and N op-amps. Is this because of some specific requirements of OP2836 that are not met?? if we don't connect the output to input of other IC then both the devices work fine. Please help.
Thanks and regards,
Nikhil
