On-state resistance is 1 Ohm maximum, which keeps insertion loss low in the audio band — the voltage divider formed by the switch resistance and the load impedance stays under 0.1 dB for a 32-Ohm headphone load. The -3 dB bandwidth extends to 380 MHz, far beyond the audio range, so the switch passes the fundamental and harmonics of a 192 kHz DAC output without roll-off. ## Supply flexibility and break-before-make Break-before-make switching ensures the two signal paths never short together during the transition, which prevents thumps or DC offsets from coupling between input sources. Housed in a 12-UFQFN package (supplier device package 12-UMLP, 1.8 mm x 1.8 mm), the FSA2276UMX occupies less than 3.3 mm² of board area — suited for space-constrained audio paths in smartphones, tablets, and wearables. Sourced to order through independent distribution; availability and current pricing confirmed at RFQ.","metaTitle":"onsemi FSA2276UMX Audio Switch DPDT, 1 Ohm, 380 MHz","metaDescription":"onsemi FSA2276UMX DPDT audio switch, 1 Ohm on-resistance, 380 MHz bandwidth, 1.65-5.5 V supply, 12-UMLP package.
