DESCRIPTION
The LM346 consists of four independent, high
gain, internally compensated, low power program-
mable amplifiers. Two external resistors (R
set
) al-
low the user to program the gain-bandwith prod-
uct, slew rate, supply current, input bias current,
input offset current and input noise. For example
the user can trade-off supply current for bandwith
or optimize noise figure for a given source resis-
tance. In a similar way other amplifier characteris-
tics can be tailored to the application.
Except for the two programmingpins at the end of
the package the LM346 pin out is the same as the
LM324 and LM348.
