General Description

The LM146 series of quad op amps 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.

For example, the user can trade-off supply current for bandwidth or optimize noise figure for a given source resistance.
