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.\n\nThe 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.\n\nKey Features\n\n\nDual 4-Channel Groups – Four switches route to DA, four route to DB\n\n8 Independent Switches – Control each switch individually via I2C\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 0x44, adjustable to 0x45/0x46/0x47 via address pins\n\nSTEMMA QT / Qwiic Connectors – Solderless I2C connection\n\nSignal Voltage – Supports analog signals up to 5V\n\n\nAlso Available\n\n\nADG728 1-to-8 Analog Matrix Switch – All 8 signals route to a single D pin\n\n\nIdeal For\n\nDual-channel analog signal routing\nStereo audio switching\nSensor multiplexing with separate output buses\nTest and measurement systems\n\n\nPackage Contents\n\n1× Adafruit ADG729 Dual 1-to-4 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":1117,"title":"Default Title","sku":"AF-5932","mpn":"ADA5932","price":18.56,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
