LM146/LM346Programmable Quad Operational AmplifiersGeneral Des criptionThe LM146 series of quad op amps consists of four independent,high gain, internally compensated, low power, programmableamplifiers. Two external resistors (RSET) allowthe user to program the gain bandwidth product, slew rate,supply current, input bias current, input offset current andinput noise. For example, the user can trade-off supplycurrent for bandwidth or optimize noise figure for a givensource resistance. In a similar way, other amplifier characteristicscan be tailored to the application. Except for the twoprogramming pins at the end of the package, the LM146pin-out is the same as the LM124 and LM148.
