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), Flexibility and Ease-of-Design analog SPST switch primarily intended for HV multiplexing HV Switches Operate From +5V Supply in ultrasound applications. OnlyEliminating Dedicated High-Voltage Supplies Eases Probe Compliance To Industry The MAX14866 operates from one only low-voltage Safety Standards supply (+5V) and does not require dedicated HV SOI TechnologyLatchup Free supplies, resulting in cost-saving and system simplification. Large Analog Input range (up to 210VPKPK) Moreover, for in-probe applications, HV supplies do not need to be associated with the MAX14866 in the probe/ 16 Independent SPST Ensure Flexibility Supporting All Possible MUX Combinations transducer head, resulting in greater safety and easier compliance with safety regulations. Switches Can Be Controlled Either Individually or Globally (Bank Selection) The MAX14866 features best-in-class performance in 30MHz SPI Interface for Individually Programming terms of bandwidth (up to 50MHz), charge injection (<100pC), the Status of the Switches and linear transmit input range (up to 210V ). The PKPK SET and CLR CMOS for global control of the low-signal switch R is typically about 7 around DSON switches (Bank Selection or Relay Replacements 0V and remains flat in the entire input range ensuring Applications) extremely good linearity. Extended Digital Logic Input Range From 1.8V to 5V The latchup-free SOI (Silicon-on-Insulator) technology High Level Of Integration and Density for and the wide analog range results in extremely high Space-Saving Applications robustness during undershoots and overshoots that 16 Channels Linear SPST switches occur in ultrasound systems due to the resonant nature 2 < 1.9mm /channel footprint (WLP) of the load. High Performance: The status of the switches can be individually controlled Low R (7 typ) Ensures Low Insertion Loss ON through a high-speed SPI interface (up to 30MHz). Daisy- R Flatness in the Entire Input Range Ensures ON chain architecture is supported. Excellent Performances In Harmonic Imaging Alternatively, switches can also be controlled with global Low Charge Injection <100pC. control signal (SET and CLR) for bank selections or relay Wide Bandwidth of Operation (Up to 50MHz) replacement applications. Low On Input Capacitance (33pF) The MAX14866 is offered in two different packages: Low Off Input Capacitance (7.7pF) wafer-level packages (WLPs) and TQFNs. The 110- Excellent Off Isolation (-75dB at 5MHz) bump WLP size is only 5.53 x 5.47mm, resulting in less 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.
