LM146/LM346

Programmable Quad Operational Amplifiers

General Description

Features

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_SET) 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.
