数据手册.pdf四路数字可编程电位计与64丝锥和I²C接口 Quad Digitally Programmable Potentiometer 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
