Description

Product Overview

The PI5A3166CEX from Diodes Incorporated is a single SPDT (single-pole double-throw) analog switch with ultra-low 2.5 ohm ON resistance in a tiny SC70-6 package. The wide 1.65V to 5.5V supply range and 5 pC charge injection make it suitable for audio signal routing and battery-powered analog switching.

Key Specifications

Function Single SPDT analog switch
ON Resistance 2.5 ohm max
Switching Time 20 ns
Supply Voltage 1.65V to 5.5V
Charge Injection 5 pC
Package SC70-6 (2×1.25mm)

Working Principle

A single control input (IN) selects between two analog paths (NC and NO) connecting to the common (COM) terminal. When IN=LOW, COM connects to NC; when IN=HIGH, COM connects to NO. Low-RON DMOS FETs minimize signal attenuation. Break-before-make switching prevents momentary shorting between NC and NO.

Applications

  • Audio signal routing
  • Sensor multiplexing
  • Battery-powered analog switching
  • Gain selection
