Notes : 1. For supply voltages less than ±15V, the absolute maximum input vol tage is equal to the supply vol tage.
2. Any of the amplifier outputs can be shorted to ground indefinitly ; however more than one should not be
simultaneously shorted as the maximum junction temperature wil l be exceeded.






Description

The LM346consists of four independent, 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 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.
