CAT5241YI-10 Datasheet PDF - Catalyst

●DESCRIPTION

●The CAT5241 is four Digitally Programmable Potentiometers (DPPs™) integrated with control logic

●and 16 bytes of NVRAM memory. Each DPP consists of a series of 63 resistive elements connected between two externally accessible end points. The tap points between each resistive element are connected to the wiper outputs with CMOS switches. A separate 6-bit control register

●FEATURES
