FSA2275AUMX

Analog Switches - Special Purpose Overview

The FSA2275AUMX is a high-fidelity audio switch manufactured by onsemi, designed for portable consumer electronics. It features a dual-pole double-throw (DPDT) configuration within a single channel architecture. The device supports low-voltage operation with a supply range of 1.65 V to 5.5 V and exhibits a maximum on-resistance of 1 Ohm. Key electrical parameters include a maximum operating frequency of 100 MHz, a maximum power supply current of 30 uA, and a maximum switching time of 100 ms. It operates reliably across a temperature range of -40°C to +85°C and utilizes a UMLP-12 surface-mount package.

Analog Switches - Special Purpose Feature Summary

• Supports negative signal swing capability for accurate audio signal routing without distortion.
• Optimized for low-power portable applications with minimal quiescent current consumption.
• Provides high bandwidth performance suitable for high-fidelity audio transmission.

Analog Switches - Special Purpose Applications

• Portable media players and digital audio recorders
• Mobile phones and smartphones for audio path switching
• Headsets and headphones with integrated control circuits

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'UMX' against the manufacturer's official datasheet to confirm the reel packaging quantity and tape specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the ordering part number with the latest onsemi documentation to avoid discrepancies in lot traceability or material composition declarations.

Analog Switches - Special Purpose Selection Notes

Select this component when a DPDT analog switch with negative swing support is required for audio signals. Compare the 1 Ohm on-resistance and 1.65 V minimum supply voltage against system requirements. Consider the UMLP-12 package size for space-constrained designs. Verify that the 100 MHz bandwidth exceeds the highest frequency component of the audio signal path.

Analog Switches - Special Purpose Part Context

This component belongs to the FSA2276 series family, which includes similar high-fidelity audio switches. The FSA2275AUMX shares functional similarities with the FSA2276 but may differ in specific electrical tolerances or pinout configurations. It is distinct from the FSA2269, which is a dual SPDT switch. The series is targeted at mobile and portable audio markets requiring low distortion and low power.
