For high current density and reliable operation, the  
MAX3864 uses gold metalization. Connections to the  
die should be made with gold wire only, using ball-  
bonding. Wedge bonding is not recommended. Die  
thickness is typically 15mils (0.375mm).

with an external capacitor, can be used to reduce this  
noise (see the Typical Application Circuit). Current gen-
