Overview
The ADG1309BRZ, produced by Analog Devices Inc., is a monolithic analog multiplexer integrated circuit. This device is part of the ADG1308/ADG1309 series, which includes 4- and 8-channel ±15 V/+12 V multiplexers. The ADG1309 specifically switches one of four differential inputs to a common differential output, controlled by 2-bit binary address lines A0 and A1. It also features an enable (EN) input to control the device's operation, allowing all channels to be switched off when disabled.
The ADG1309 is designed for applications requiring high signal integrity and low power consumption, making it suitable for a variety of electronic systems.
