FSA551UCX Description

Short technical summary and product information.

The FSA551UCX from On Semiconductor is a dual Single Pole Single Throw (SPST) analog switch designed for audio applications. This component offers a bandwidth of 240MHz and a low on-state resistance of up to 600mOhm.

 

Operating within a supply voltage range of 1.5V to 3V, the FSA551UCX is suitable for various portable and low-voltage systems. The device is specified for an operating temperature range of -40°C to 85°C.

 

Packaged in a compact 9-WLCSP (Wafer Level Chip Scale Package) with dimensions of 1.22x1.22mm, it is designed for surface mounting. This small footprint makes it ideal for space-constrained designs.

 

The switch circuit is SPST, and it functions as a 1:1 multiplexer, allowing for efficient signal routing in audio paths.
