Analog Devices / Maxim Integrated MAX14866 16チャンネル高電圧アナログスイッチ
Maxim Integrated MAX14866 16-Channel High-Voltage Analog Switch is ideal for HV multiplexing in ultrasound applications and operates from only one +5V low-voltage supply. MAX14866には専用のHV電源が不要です。プローブ内のアプリケーションには、プローブ/トランスデューサヘッド内のMAX14866に関連付ける必要があるHV電源は不要です。これによって、コスト削減、安全規制への準拠が容易になるシステムの簡素化になります。 このスイッチには、ベストインクラスの帯域幅（最大500Mhzまで）性能、電荷注入（<100pC）、リニア送信入力範囲（最大210VPKPK）があります。低信号スイッチRDSON は、一般に0Vを中心としておよそ7Ωで、入力範囲全体でフラットなままで、極めて良好な直線性が保証されます。
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.
