AD5112BCPZ80-1-RL7 Datasheet PDF - ADI

●GENERAL DESCRIPTION

●The AD5110/AD5112/AD5114 provide a nonvolatile solution for 128-/64-/32-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the A, B, and W pins. The low resistor tolerance, low nominal temperature coefficient and high bandwidth simplify open-loop applications, as well as tolerance matching applications.
