Overview
The ADG758BCP from Analog Devices Inc. is a low voltage, CMOS analog multiplexer designed for high performance and low power consumption. This device features eight single channels, allowing it to switch one of eight inputs (S1–S8) to a common output, D, based on the 3-bit binary address lines A0, A1, and A2. An enable input (EN) is provided to enable or disable the device, with all channels switched off when disabled. The ADG758BCP is ideal for battery-powered, portable instruments due to its operating supply range of 1.8 V to 5.5 V and low power dissipation.
