Overview
The ADG726BSUZ-REEL, produced by Analog Devices Inc., is a 16-channel analog multiplexer designed for high-performance applications. This device is part of the ADG726 series, which features monolithic, complementary metal oxide semiconductor (CMOS) technology. It operates by switching one of 16 inputs to a common output, controlled by 4-bit binary address lines A0, A1, A2, and A3. The ADG726 is versatile, supporting both single-supply (+1.8 V to +5.5 V) and dual-supply (±2.5 V) operations, making it suitable for a wide range of applications. On-chip latches facilitate easy interfacing with microprocessors, and the device can be configured for differential operation by tying CSA and CSB together. An enable input (EN) allows for the device to be enabled or disabled, with all channels switched off in the disabled state.
