* AD630 SPICE Macro-model
* Description: Amplifier
* Generic Desc: Bipolar, Balanced Modulator/Demod
* Developed by: ARG / PMI
* Revision History: 08/10/2012 - Updated to new header style
* 2.0
* Changed R1 and R2 to 20k ohms to meet comparator input voltage spec.
* Changed E1 gain to 100k to better meet minimum comparator diff. input
* spec.
* Changed DZ breakdown from 30V to 50V.
* Changed Ios1,Ios2 to 25E-9 and changed polarity.
