# FSA2268UMX (Component) ## Description Audio Switch IC 2 Channel 10-UMLP (1.4x1.8) The FSA2268UMX is a dual SPDT analog switch from ON Semiconductor (formerly Fairchild) that operates over a low supply voltage range (1.65 V to 4.3 V). It provides high-speed signal switching with ultra-low on-resistance (~0.4 Ω typical), making it suitable for audio, data, and general analog signal routing. It is designed using a break-before-make switching architecture, meaning it disconnects the current path before connecting another, preventing short circuits or signal glitches. Key Features Dual SPDT analog switch configuration (2 channels) Low operating voltage: 1.65 V to 4.3 V Ultra-low on-resistance (~0.4 Ω typical @ 3 V) High-speed switching (-3 dB bandwidth > 50 MHz) Break-before-make switching (prevents signal overlap) TTL-compatible control inputs Very low power consumption (low quiescent current) High ESD protection (up to 16 kV HBM) Small 10-pin µMLP/UMLP surface-mount package Operating temperature: -40°C to +85°C Typical Applications Smartphones and tablets Audio signal switching circuits Digital cameras Laptops and portable devices TVs, set-top boxes, LCD systems General-purpose analog signal routing ## Component Details - **Owner:** adrian95 - **Created:** 5/6/2026 - **Last Updated:** 5/6/2026 - **Visibility:** Public - **Datasheet URL:** https://rocelec.widen.net/view/pdf/h0vdcpbecl/FAIRS34282-1.pdf?t.download=true&u=5oefqw - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Name:** Fairchild Semiconductor - **Part Type:** Electromechanical Components - **Manufacturer Part Number:** FSA2268UMX ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
