The IBIS model provided on our website (www.analog.com/ad5142) is designed only
for LFCSP package.
Could you please provided an IBIS file for DSO package – 16 ld TSSOP?
LFCSP and TSSOP have same pinout, you can use the same IBIS file.
You just need to reorder manually the pins to fit for the TSSOP package.
