MAX14866  
16-Channel, High-Voltage Analog Switch  
without High-Voltage Supply Requirement  
General Description  
Benefits and Features  
The MAX14866 is a 16-channel, high-voltage (HV),  
analog SPST switch primarily intended for HV multiplexing  
in ultrasound applications.  
● Flexibility and Ease-of-Design  
• HV Switches Operate From +5V Supply  
Only–Eliminating Dedicated High-Voltage Supplies  
Eases Probe Compliance To Industry  
Safety Standards  
The MAX14866 operates from one only low-voltage  
supply (+5V) and does not require dedicated HV  
supplies, resulting in cost-saving and system simplification.  
Moreover, for in-probe applications, HV supplies do not  
need to be associated with the MAX14866 in the probe/  
transducer head, resulting in greater safety and easier  
compliance with safety regulations.  
• SOI Technology–Latchup Free  
• Large Analog Input range (up to 210VPKPK)  
• 16 Independent SPST Ensure Flexibility  
Supporting All Possible MUX Combinations  
• Switches Can Be Controlled Either Individually  
or Globally (Bank Selection)  
• 30MHz SPI Interface for Individually Programming  
the Status of the Switches  
• SET and CLR CMOS for global control of the  
switches (Bank Selection or Relay Replacements  
Applications)  
The MAX14866 features best-in-class performance in  
terms of bandwidth (up to 50MHz), charge injection (<100pC),  
and linear transmit input range (up to 210V ). The  
PKPK  
low-signal switch R  
is typically about 7Ω around  
DSON  
0V and remains flat in the entire input range ensuring  
extremely good linearity.  
• Extended Digital Logic Input Range From 1.8V to 5V  
The latchup-free SOI (Silicon-on-Insulator) technology  
and the wide analog range results in extremely high  
robustness during undershoots and overshoots that  
occur in ultrasound systems due to the resonant nature  
of the load.  
● High Level Of Integration and Density for  
Space-Saving Applications  
• 16 Channels Linear SPST switches  
2
• < 1.9mm /channel footprint (WLP)  
● High Performance:  
The status of the switches can be individually controlled  
through a high-speed SPI interface (up to 30MHz). Daisy-  
chain architecture is supported.  
• Low R  
(7Ω typ) Ensures Low Insertion Loss  
ON  
• R  
Flatness in the Entire Input Range Ensures  
ON  
Excellent Performances In Harmonic Imaging  
• Low Charge Injection <100pC.  
• Wide Bandwidth of Operation (Up to 50MHz)  
• Low On Input Capacitance (33pF)  
Alternatively, switches can also be controlled with global  
control signal (SET and CLR) for bank selections or relay  
replacement applications.  
The MAX14866 is offered in two different packages:  
wafer-level packages (WLPs) and TQFNs. The 110-  
bump WLP size is only 5.53 x 5.47mm, resulting in less  
Low Off Input Capacitance (7.7pF)  
• Excellent Off Isolation (-75dB at 5MHz)  
Excellent Crosstalk Performances (-62dB at 5MHz)  
2
than 1.9mm /channel footprint and allowing for very high  
levels of integration, which is especially beneficial for  
in-probe applications.  
Ordering Information appears at end of data sheet.  
The size of the TQFN package is an industry standard  
48-pin, 7mm x 7mm package.  
Applications  
● Medical Ultrasound Imaging  
● Relays replacements  
● NDT  
● Printers
