产品简介

CXAS42177是一种双向、单极/双掷（SPTT）CMOS模拟开关，设计用于从一个+2.5V到+5.0V电源工作。它具有高带宽（400MHz）和低导通电阻（4Ω类型），开关可以处理负信号低至-2.0V。
CXAS42177的特点是开关之间的保证通电电阻匹配为0.1Ω（典型值），信号范围内的保证通电电阻平坦度为1Ω（典型值）。这确保了切换音频信号时具有良好的线性度和低失真。
CXAS42177是一个承诺的单刀双掷（SPTT）开关，由一个常开（NO）和一个常闭（NC）开关组成。此配置可用作2对1多路复用器。

   产品概述 返回TOP

The CXAS42177 is a bidirectional, single-pole/double-throw (SPDT) CMOS analog switch designed to operate from a single +2.5V to +5.0V supply. It features high bandwidth (400MHz) and low on-resistance (4Ω TYP), and the switches can handle negative signal down to -2.0V.

The CXAS42177 features a guaranteed on-resistance matching of 0.1Ω (TYP) between switches and a guaranteed on-resistance flatness of 1Ω (TYP) over the signal range. This ensures excellent linearity and low distortion when switching audio signals.

The CXAS42177 is a committed single-pole/double-throw (SPDT) switch that consists of one normally open (NO) and one normally closed (NC) switches. This configuration can be used as a 2-to-1 multiplexer.

The CXAS42177 is available in Green SOT-23-6 package.
