Analog Devices / Maxim Integrated MAX14866 16-Channel High-Voltage Analog Switch

Analog Devices MAX14866 16-Channel High-Voltage Analog Switch is ideal for HV multiplexing in ultrasound applications and operates from only one +5V low-voltage supply. The Analog Devices MAX14866 doesn't require dedicated HV supplies, and for in-probe applications, HV supplies do not need to be associated with the MAX14866 in the probe/transducer head. This results in cost-saving and system simplification with easier compliance with safety regulations. 

The switch has best-in-class bandwidth (up to 500MHz) performance, charge injection (<100pC), and linear transmit input range (up to 210VPKPK). The low-signal switch RDSON is typically about 7Ω around 0V and remains flat in the entire input range ensuring extremely good linearity.
