Adafruit ADG729 Dual 1-to-4 Analog Matrix Switch

Analog switches offer a compact, energy-efficient alternative to traditional relays, reducing mechanical wear and extending switch longevity. The Adafruit ADG729 enables seamless connections between two sets of four analog signals, functioning similarly to 8 mechanical switches.

This surface-mount component eliminates intricate soldering by utilizing a breakout board, allowing for easy signal handling up to 5V. Leveraging I2C communication, the switch precisely controls channel activation.

Features include eight independent bidirectional switches, break-before-make safeguards, and multiple connection configurations. Adjust the default I2C address across four options, facilitating versatile setups.

Note: Ensure Vin power is higher than the highest analog voltage; negative voltages are incompatible. Ideal for signal routing, not power distribution, it ensures near-instant switching speeds without current-sourcing limitations.

Compatible with STEMMA QT and SparkFun Qwiic systems, this device integrates effortlessly into broader networks, facilitating quick, solderless connections with development boards and diverse accessories.
