LM146/LM346
Programmable Quad Operational Amplifiers
General Description
The LM146 series of quad op amps consists of four indepen-
dent, high gain, internally compensated, low power, pro-
grammable amplifiers. Two external resistors (R
) allow
the user to program the gain bandwidth product, slew rate,
supply current, input bias current, input offset current and in-
put noise. For example, the user can trade-off supply current
for bandwidth or optimize noise figure for a given source re-
sistance. In a similar way, other amplifier characteristics can
be tailored to the application. Except for the two program-
ming pins at the end of the package, the LM146 pin-out is
the same as the LM124 and LM148.
