TS5A23157 Dual Single Pole Double Throw Analog Switch Module

TS5A23157 Dual Single Pole Double Throw Analog Switch Module is a high-speed, low-voltage analog switch module based on the TS5A23157 IC. It features two independent SPDT (Single Pole Double Throw) switches that support rail-to-rail analog signal switching. Ideal for signal routing, audio multiplexing, sensor interface, and analog I/O expansion in embedded systems.

Key Features:

• Dual SPDT Switches: Two independently controlled analog switches in one module.
• Low ON-State Resistance: Typical R_ON of 0.5Ω ensures minimal signal distortion.
• Wide Voltage Range: Operates from 1.65V to 5.5V supply.
• Low Power Consumption: Ideal for battery-powered and portable devices.
• High Signal Bandwidth: Suitable for analog and digital signal switching up to MHz range.

Technical Specifications:
