The Adafruit ADG728 1-to-8 Analog Matrix Switch provides a solid-state alternative to relays, offering a smaller, lower-power solution for connecting between eight analog signals, akin to using a set of 8 mechanical switches. This breakout board simplifies the usage of the ADG728 switch for signals up to 5V, eliminating the need for intricate soldering.

Features:

1. Single 8-to-1 Analog Matrix Switch: Enables connection between eight analog signals, offering bidirectional signal routing options.
2. I2C Interface: Utilizes I2C communication protocol to select which of the 8 channels switches to turn on or off, connecting that channel to the single analog D pin, providing simple control and configuration.
3. Instantaneous Switching: Analog switches offer near-instant switch time of about 100nS, ensuring rapid signal switching without mechanical wear-out.
4. Break-Before-Make Guarantee: Ensures deselected switches will open before selected switches close, preventing signal interference and maintaining signal integrity.
5. 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.

Specifications:

1. Supply Voltage: 2.7 V to 5.5 V Single Supply
2. On Resistance: 2.5 (Typical), 0.75 On-Resistance Flatness
3. Leakage Currents: 100 pA
4. Matrix Configuration: Single 8-to-1 Matrix Switch
5. Power-On Reset: Included
