CAT5241WI10

四路数字可编程电位计（ DPP⑩ ）与64丝锥和IC接口 Quad Digitally Programmable Potentiometer DPP™ with 64 Taps and I²C Interface

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
