Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductors system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore ( ), the underscore ( ) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore ( ). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild questions onsemi.com.

This product FSA5157 Features Less than 12 A I Current CCT has been designed for switching audio signals in applica- When S Input is Lower than V CC tions such as cell phones and portable media players. 0.25 Maximum R Flatness for +2.7V Supply ON The ultra-low 0.4 impedance, sub-A current consump- 1.0 x 1.45mm 6-Lead MicroPak Package tion, and 1.65V to 4.3V operating voltage range makes Broad V Operating Range: 1.65V to 4.3V CC this product ideal for battery-powered applications. The Low THD (0.02% Typical for 32 Load) FSA5157 also features bi-directional operation and High-Current Handling Capability break-before-make functionality. This device is fully specified for operation at 1.8V, 2.5V, and 3.3V. (350mA Continuous Current Under 3.3V Supply) Control Logic is 1.8V CMOS Logic Compatible A growing number of applications require the voltage applied to the select input to be lower than the V CC Applications applied. Under this condition, most switches would typi- cally consume over 100A of current. This would be an Cellular Phone unacceptable level for battery-powered applications. The PDA FSA5157 is designed to minimize current consumption Portable Media Player under this condition. The I is specified for <12A under CCT a worst-case condition of V = 4.3V and V = 1.8V.
