The Adafruit ADG729 Dual 1-to-4 Analog Matrix Switches provide a solid-state alternative to relays, offering smaller size, lower power consumption, and increased durability. This breakout board enables easy usage of the ADG729 switch for connecting between two sets of four analog signals, simulating 8 mechanical switches without the need for intricate soldering.
Features:
- Dual 1-to-4 Analog Matrix Switches: Allows connection between two sets of four analog signals, providing bidirectional signal routing options.
- I2C Interface: Utilizes I2C communication protocol to select which of the 8 channels switches to turn on or off, offering simple control and configuration.
- Instantaneous Switching: Analog switches offer near-instant switch time of about 100nS, ensuring rapid signal switching without mechanical wear-out.
- Break-Before-Make Guarantee: Ensures deselected switches will open before selected switches close, preventing signal interference and maintaining signal integrity.
- STEMMA QT Form Factor: Custom-made PCB in the STEMMA QT form factor for easy interfacing and compatibility with SparkFun Qwiic I2C connectors, facilitating solderless connections with development boards and other sensors and accessories.
