CXAS42189是一个双、双向、单极/双掷（SPTT）CMOS模拟开关，设计用于从1.8V到5.5V的单一电源。它具有高带宽（300MHz）和低导通电阻（4.5Ω典型值），有针对性地应用于音频交换。
CXAS42189具有保证开关之间的电阻匹配（最大0.3Ω）和保证信号范围（2.3Ω典型值）内的电阻平坦度。这确保了切换音频信号时具有良好的线性度和低失真。
CXAS42189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。
CXAS42189有绿色的WLCSP-2.0×1.5-10B和MSOP-10包装。

产品概述 返回TOP
The CXAS42189 is a dual, bidirectional, single-pole/double-throw (SPDT) CMOS analog switch designed to operate from a single 1.8V to 5.5V supply. It features high-bandwidth (300MHz) and low on-resistance (4.5Ω TYP), targeted applications for audio switching.
CXAS42189 features guaranteed on-resistance matching (0.3Ω MAX) between switches and guaranteed on-resistance flatness over the signal range (2.3Ω TYP). This ensures excellent linearity and low distortion when switching audio signals.
The CXAS42189 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.
CXAS42189 is available in Green WLCSP-2.0×1.5-10B and MSOP-10 packages.
