LM346 Datasheet PDF

National Semiconductor LM346

The LM146 series of quad op amps consists of four independent, high gain, internally compensated, low power, programmable amplifiers. For example, the user can trade-off supply current for bandwidth or optimize noise figure for a given source resistance.

GENERAL DESCRIPTION

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. 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 LM146 pin-out is the same as the LM124 and LM148.
