General Description
The LM146 seriesof quadop amps consistsof four indepen-
dent, high gain, internally compensated, low power, pro-
grammable amplifiers. Two external resistors (RSET) allow
the userto program the gain bandwidth product, slew rate,
supply current, input bias current, input offset current andin-
put noise. For example,the user can trade-off supply current
for bandwidthor optimize noise figurefora given sourcere-
sistance.Ina similar way, other amplifier characteristics can tailoredto the application. Exceptfor the two program-
ming pinsat the endof the package, the LM146 pin-outis
the sameas the LM124 and LM148.
