DESCRIPTION
The X9430 is a monolithic CMOS IC that incorporates two operational amplifiers and two nonvolatile digitally controlled potentiometers. The amplifiers are CMOS differential input voltage operational amplifiers with near rail-to-rail outputs. All pins for the two amplifiers are brought out of the package to allow combining them with the potentiometers or using them as complete stand-alone amplifiers.
