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 programming pins at the end of
the package the LM346 pin out is the same as the
LM324 and LM348.
PROGRAMMING EQUATIONS :
Total supply current = 1mA (I
set
= 10碌A(chǔ))
Gain bandwith product = 1MHz (I
set
= 10碌A(chǔ))
Slew rate = 0.5V/碌s (I
set
= 10碌螒)
Input bias current
鈮?0nA

= 10碌螒)
