GENERAL DESCRIPTION
Particularly, adjacent sensor suppression (ASS) function ensures only one channel active each time. The range of power is 2.8V ~ 3.6V. Low-power operation makes the CP2508 ideal for battery-operated systems, such as multimedia portable product. The CP2508 is specified over the -40℃ to +85℃ temperature range. QFN-32 - 40 oC ~ 85 oCFEATURES
