DESCRIPTION  
The LM346consists of fourindependent, high gain,  
internally compensated, low power programmable  
amplifiers. Two external resistors (Rset) allow the  
user to program the gain-bandwith product, slew  
rate, supply current, input bias current, input offset  
current and input noise. For example the user can  
trade-off supply current for bandwidth or optimize  
noise figure for a given source resistance. In a simi-  
lar way other amplifier characteristics can be  
tailored to the application.
