Dual 4:2 crosspoint switch for audio and video routing
The switch operates from a single supply of 2.7 V to 5.5 V or dual supplies of ±2.7 V to ±5.5 V, covering common analog rails in mixed-signal systems. On-state resistance is rated 80 ohms max, and the device is specified over the industrial temperature range of -40°C to 85°C.
Break-before-make and clickless — why they matter for audio
Break-before-make ensures that the switch opens one path before closing the next, preventing momentary shorting of two signal sources. For audio routing, this avoids audible pops and clicks during channel changes. The clickless feature further suppresses transient noise by controlling the internal gate drive timing — it is not a mute function, but it reduces the charge injection that causes switching transients. Together, these features make the MAX4570EAI+ suitable for audio mixers, AV receivers, and studio patch bays where glitch-free switching is required.
Supply voltage flexibility and package
The device accepts a single supply from 2.7 V to 5.5 V or dual supplies from ±2.7 V to ±5.5 V. The 28-SSOP package (0.209-inch body width, 5.30 mm) is surface mount.
Lifecycle and sourcing
The MAX4570EAI+ is listed as Active in production with ROHS3 compliance. For a BOM line that needs this dual 4:2 crosspoint switch, the part is available to order through independent distribution.
