Texas Instruments LM146
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. Except for the two programming pins at the end of the package, the LM146 pin-out is the same as the LM124 and LM148.FEATURES

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. Connection Diagram Figure 1.
