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 Semiconductor’s 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 has been designed for switching audio signals in applications such as cell phones and portable media players. The ultra-low 0.4Ω impedance, sub-μA current consumption, and 1.65V to 4.3V operating voltage range makes this product ideal for battery-powered applications. The FSA5157 also features bi-directional operation and break-before-make functionality. This device is fully specified for operation at 1.8V, 2.5V, and 3.3V. When S Input is Lower than VCC ■ 0.25Ω Maximum RON Flatness for +2.7V Supply ■ 1.0 x 1.45mm 6-Lead MicroPak™ Package ■ Broad VCC Operating Range: 1.65V to 4.3V ■ Low THD (0.02% Typical for 32Ω Load) ■ High-Current Handling Capability (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 VCC applied. Under this condition, most switches would typically consume over 100μA of current. This would be an unacceptable level for battery-powered applications. The FSA5157 is designed to minimize current consumption under this condition. The ICCT is specified for
