*EL5170 and EL5370 -- Model Rev. A 10/07/2003
*low power, wide bandwidth differential driver---110MHz for fixed gain of 2
*The AC response for this model is based on Vs=+/-5V and RLD=200
*SR and open loop gain are modeled. The enabled/disabled function is not modeled.
*The pinout is based on EL5170 package
*The output short circuit current is not modeled
