Overview
The ADG708CRU from Analog Devices Inc. is a low-voltage, CMOS analog multiplexer that comprises eight single channels. This device switches one of eight inputs (S1 to S8) to a common output, D, based on the 3-bit binary address lines A0, A1, and A2. An EN input is used to enable or disable the device, with all channels switching off when disabled. The ADG708CRU is designed for low power consumption and operates over a supply range of 1.8 V to 5.5 V, making it ideal for battery-powered, portable instruments. It features break-before-make switching action to prevent momentary shorting when switching channels.
