The X9438 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. The digitally controlled potentiometers consist of a series string of 63 polycrystalline resistors that behave as standard integrated circuit resistors.
The X9438 is an integrated microcircuit that incorporates two voltage operational amplifiers and two nonvolatile digitally controlled potentiometers (XDCP). The amplifiers are designed for low-voltage operation with rail-to-rail outputs, while the potentiometers utilize a MOS Performance series string of 63 polycrystalline resistors.
The analog supplies V+/V- must be between 2.7V and 5.5V.
Each array contains 63 discrete resistive segments that are connected in series.
