| CMOS/DMOS Wideband Dual SPDT Analog Switch CORPORATION CWB2269 FEATURES DESCRIPTION The CWB2269 is a Precision Dual Single Pole, Double Throw Analog Switch for precision applications in instrumentation, communications and process control where low leakage and high speed switching are required. Designed on the Calogic CMOS/DMOS process this analog switch takes advantage of high speed DMOS switching FETs combined with low voltage CMOS technology in a monolithic structure.
