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 similar way other amplifier characteristics can be tailored to the application. Except for the two programming pins at the end of the package the LM346 pin out is the same as the LM324 and LM348.
