DESCRIPTION
The LM346 consists 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.
