DESCRIPTION
The LM346consistsof fourindependent,highgain,
internally compensated, low power programmable
amplifiers. Two external resistors (R
set
) allow the
user to program the gain-bandwith 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
noisefigurefora given sourceresistance.Inasimi-
lar way other amplifiercharacteristics can be
tailored to the application.
Except for thetwo programming pins at the end of
the packagethe LM346 pin out is the same as the
LM324and LM348.
