Product Summary

The LM346N is an independent, high gain, internally compensated, low power, programmable amplifier. Two external resistors (RSET) allow the user to program the gain bandwidth 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, The LM346N characteristics can be tailored to the application. Except for the two programming pins at the end of the package, the LM346N pin-out is the same as the LM124 and LM148.
