Analog Devices / Maxim Integrated MAX14866 16通道高压模拟开关
Maxim Integrated MAX14866 16通道高压模拟开关非常适合用于超声应用中的高压多路复用，在单+5V低电源电压下工作。MAX14866无需专用的高压电源，对于探头内应用，无需将高压电源与探头内的MAX14866相关联。这样可以降低成本、简化系统，并更加轻松地符合安全法规要求。 该开关具有同类最佳的带宽（高达500MHz）性能、电荷注入 (<100pC) 以及线性传输输入范围（高达210VPKPK）。低信号开关RDSON通常在0V左右约为7Ω，并在整个输入范围内保持平坦，以确保出色的线性度。
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.
