Overview
The ADG428BRZ-REEL is a monolithic CMOS analog multiplexer produced by Analog Devices Inc. This device comprises eight single channels and features on-chip address and control latches, facilitating microprocessor interfacing. The ADG428 switches one of eight inputs to a common output 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 switched OFF when disabled. The TTL-compatible address and control inputs make this part suitable for bus-controlled systems such as data acquisition systems, process controls, avionics, and Automatic Test Equipment (ATEs).
