Key Features
- SPDT analog switch with 64 dB off-state isolation for clean signal separation in RF and audio paths
- 0.06 Ω on-resistance matching between switch states for minimal signal distortion
- 12-ball WLCSP package for ultra-compact, high-density portable PCB integration
- Single-channel SPDT topology in a 2-function configuration for flexible routing
- Low on-resistance enables low insertion loss in audio, video, and high-frequency signal paths
Applications
The MAX4684EBC+ is used in portable consumer electronics such as smartphones, tablets, and wearable devices where antenna switching, audio jack routing, or baseband signal muxing must be implemented in minimal board space. Its 64 dB off-state isolation makes it suitable for RF front-end applications where signal bleed between switched paths must be suppressed. Industrial and medical handheld instruments also use it for precision analog signal routing where low on-resistance and tight resistance matching prevent measurement errors.

Frequently Asked Questions
What off-state isolation does the MAX4684EBC+ provide, and why does that matter for RF signal switching?
The MAX4684EBC+ provides 64 dB nominal off-state isolation. In an RF switching application, 64 dB of isolation means the signal on the unselected path is attenuated by a factor of 1,600,000:1 in power, preventing leakage from interfering with the active signal path. This level of isolation is important in antenna diversity switches and receive-path selectors operating up to several hundred megahertz.
How closely matched is the on-resistance between the two switch positions of the MAX4684EBC+?
The MAX4684EBC+ specifies on-resistance matching of 0.06 Ω nominal between its two switch states. This tight matching ensures that signal gain and insertion loss remain consistent regardless of which switch position is active, which is critical in audio calibration circuits and instrumentation switches where path-dependent gain variation would cause measurement errors.
What package does the MAX4684EBC+ come in, and how does it compare to a standard SOT-23 in terms of board area?
The MAX4684EBC+ is housed in a 12-ball WLCSP (wafer-level chip-scale package). A WLCSP is essentially the bare die with solder balls, making it significantly smaller than a SOT-23 footprint by typically 50% to 70% in board area. This size advantage is valuable in smartphones and wearables where every square millimeter of PCB space is contested.
Is the MAX4684EBC+ still a viable choice for new designs, given its introduction date of 2001?
The MAX4684EBC+ has a YTEOL (years to end of life) of 10 from its database entry and was introduced in January 2001. Designers should verify current lifecycle status with Analog Devices or authorized distributors before committing to new designs, and evaluate whether newer SPDT switches with lower on-resistance or smaller WLCSP footprints better match current requirements.
