Description as follow:

The LM146J is a Programmable Quad Operational Amplifier. The LM146J consists of four independent, high gain, internally compensated, low power, programmable amplifiers. 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. Except for the two programming pins at the end of the package, the LM146J pin-out is the same as the LM124 and LM148.
