CXAS42198是一个双单刀双掷（SPTT）模拟开关，设计用于从一个+1.8V到+4.2V电源工作。目标应用包括电池供电设备，受益于CXAS42198的低导通电阻（0.5Ω）和快速开关速度（tON=17ns，tOFF=27.5ns）。
CXAS42198在开关之间具有良好的电阻匹配（最大0.18Ω），并确保在所有信号范围（0.1Ω典型值）内具有良好的电阻平坦度。这确保了切换音频信号时具有良好的线性度和低失真。
CXAS42198是一个由两个常开（NO）和两个常闭（NC）开关组成的承诺型双单刀双掷（SPTT）。此配置可用作双2对1多路复用器。
•电压运行：1.8V至4.2V
•超低导通电阻：4.2V时为0.5Ω（典型值）
•快速切换时间17纳秒
飞行时间27.5ns
•高关隔离度：1MHz时为-58dB
•低串扰：1MHz时为-104dB
•轨对轨输入和输出操作
•1.8V逻辑兼容控制引脚
•接通前断开开关

产品概述 返回TOP
The CXAS42198 is a dual single-pole/double-throw (SPDT) analog switch that is designed to operate from a single +1.8V to +4.2V power supply. Targeted applications include battery powered equipment that benefit from CXAS42198’s low on-resistance (0.5Ω) and fast switching speeds (tON = 17ns, tOFF = 27.5ns).
CXAS42198 has excellent on-resistance matching (0.18Ω MAX) between switches and guarantees excellent on-resistance flatness over all signal range (0.1Ω TYP). This ensures excellent linearity and low distortion when switching audio signals.
The CXAS42198 is a committed dual single-pole/double-throw (SPDT) that consist of two normally open (NO) and two normally close (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer.
CXAS42198 is available in Green TQFN-1.8×1.4-10L package.
