产品简介

CXAS42176是一个通过双单刀双掷（SPTT）模拟开关的负信号，设计用于从一个+2.5V到+5V电源工作。目标应用包括得益于CXAS42176超低导通电阻（0.6Ω）和快速开关速度（tON=17ns，tOFF=24ns）的电池供电设备。
CXAS42176在开关之间具有良好的电阻匹配（最大0.22Ω），并确保在所有信号范围（最大0.22Ω）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。
CXAS42176是一个承诺的双单刀双掷（SPTT），由两个常开（NO）和两个常闭（NC）开关组成。此配置可用作双2对1多路复用器。
CXAS42176可以以非常低的失真通过-2V接地参考信号。

   产品概述 返回TOP

The CXAS42176 is a negative signal passing dual single-pole/double-throw (SPDT) analog switch that is designed to operate from a single +2.5V to +5V power supply. Targeted applications include battery powered equipment that benefit from CXAS42176’s ultra low on-resistance (0.6Ω) and fast switching speeds (tON = 17ns, tOFF = 24ns).

The CXAS42176 has excellent on-resistance matching (0.22Ω MAX) between switches and guarantees excellent on-resistance flatness over all signal range (0.22Ω MAX). This ensures excellent linearity and low distortion when switching audio signals.

The CXAS42176 is a committed dual single-pole/doublethrow (SPDT) that consist of two normally open (NO) and two normally closed (NC) switches. This configuration can be used as a dual 2-to-1 multiplexer.

The CXAS42176 can pass -2V ground referenced signal with very low distortion.

The CXAS42176 is available in Green UTQFN- 1.8×1.4-10L package. It operates over an ambient temperature range of -40℃ to +85℃.
