GENERAL DESCRIPTION
The ADG798-KGD is a member of a growing series of high The ADG798-KGD is a low voltage, CMOS, analog multiplexer temperature qualified products offered by Analog Devices, Inc. designed to operate at very high temperatures up to 210°C. The For a complete selection table of available high temperature ADG798-KGD switches one of eight inputs (S1 to S8) to a products, see the high temperature product list and qualification common output (D) as determined by the 3-bit binary address data available at www.analog.com/hightemp. lines (A0, A1, and A2). An EN input on the device enables or Additional application and technical information can be found disables the device. When the device is disabled, all channels are in the ADG798 data sheet.
