Product Details
The ADG798 is a low voltage, CMOS, analog multiplexer designed to operate at very high temperatures up to 210°C. The ADG798 switches one of eight inputs (S1 to S8) to a common output, D, as determined by the 3-bit binary address lines A0, A1, and A2. An EN input on the device is used to enable or disable the device. When the device is disabled, all channels are switched off.
The ADG798 features low power consumption and a 3.3 V to 5.5 V operating supply range. All channels exhibit break-before-make switching action, preventing momentary shorting when switching channels. These switches are designed with an enhanced submicron process that provides low power dissipation, high switching speed and very low on resistance.
The on resistance (RON) is a maximum of 10 Ω and is closely matched between switches and very flat over the full signal range. The ADG798 operates equally well as either a multiplexer or a demultiplexer and has an input signal range that extends to the supplies.
This mux is available in a 16-lead ceramic flat package (FLATPACK) and a 16-lead ceramic flat package with reverse formed gullwing leads (FLATPACK_RF). Both of the flat packages have an operating temperature range of −55°C to +210°C. A 16-lead TSSOP package is also available that has an operating temperature range of −55°C to +175°C. All packages are designed for robustness at extreme temperatures, and are qualified for 1000 hours of continuous operation at the maximum temperature rating.
The ADG798 is a member of a growing series of high temperature qualified products offered by Analog Devices, Inc. For a complete selection table of available high temperature products, see the high temperature product list and qualification data available at http://www.analog.com/hightemp.
