## Description

The Adafruit ADG729 is a solid-state dual 1-to-4 analog matrix switch controlled over I2C. It provides two independent groups of 4 switches — four channels routed to the DA pin and four channels routed to the DB pin — giving you 8 total switches in a compact package. Unlike relays, analog switches have no moving parts, won't wear out, and switch in approximately 100 ns. The ADG729 features 8 independent switches rather than a simple multiplexer, so you can turn on multiple switches simultaneously within each group to merge signals together, or use each group as a traditional SP4T selector. The signal path is fully bidirectional. Break-before-make switching ensures clean transitions between channels. Key Features Dual 4-Channel Groups – Four switches route to DA, four route to DB 8 Independent Switches – Control each switch individually via I2C Fast Switching – Approximately 100 ns switch time Break-Before-Make – Deselected switches open before selected switches close Bidirectional – Signal path works in either direction Configurable Address – Default 0x44, adjustable to 0x45/0x46/0x47 via address pins STEMMA QT / Qwiic Connectors – Solderless I2C connection Signal Voltage – Supports analog signals up to 5V Also Available ADG728 1-to-8 Analog Matrix Switch – All 8 signals route to a single D pin Ideal For Dual-channel analog signal routing Stereo audio switching Sensor multiplexing with separate output buses Test and measurement systems Package Contents 1× Adafruit ADG729 Dual 1-to-4 Analog Matrix Switch Breakout Important: The Vin power pin must be at least as high as the highest analog voltage you want to switch. This switch cannot handle negative voltages and is designed for signal routing only — not for sourcing or sinking power (more than a few mA).
