Unlike relays, analog switches have no moving parts, won't wear out, and switch in approximately 100 ns. Use it to route up to 8 analog signals (up to 5V) to a single common pin, or vice versa — the signal path is fully bidirectional.\n\nThe ADG728 features 8 independent switches rather than a simple multiplexer, so you can turn on multiple switches simultaneously to merge signals together, or use it as a traditional SP8T selector. Break-before-make switching ensures clean transitions between channels.\n\nKey Features\n\n\n8 Independent Switches – Route any combination of 8 signals to a single D pin\n\nI2C Controlled – Simple digital control of all 8 channels\n\nFast Switching – Approximately 100 ns switch time\n\nBreak-Before-Make – Deselected switches open before selected switches close\n\nBidirectional – Signal path works in either direction\n\nConfigurable Address – Default 0x4C, adjustable to 0x4D/0x4E/0x4F via address pins\n\nReset Pin – Instantly set all switches to open\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection\n\nSignal Voltage – Supports analog signals up to 5V\n\n\nAlso Available\n\n\nADG729 Dual 1-to-4 Analog Matrix Switch – Two independent 4-channel groups with separate D pins\n\n\nIdeal For\n\nAnalog signal routing and selection\nSensor multiplexing\nAudio signal switching\nTest and measurement systems\n\n\nPackage Contents\n\n1× Adafruit ADG728 1-to-8 Analog Matrix Switch Breakout\n\n\n\nImportant: 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).\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":1118,"title":"Default Title","sku":"AF-5899","mpn":"ADA5899","price":19.41,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
