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.

FSA5157 — 0.4Ω Low-Voltage SPDT Analog Switch ©2006 Fairchild Semiconductor Corporation www.fairchildsemi.com FSA5157 Rev. 1.0.3 FSA5157 0.4Ω Low-Voltage SPDT Analog Switch
Features
■ Typical 0.4Ω On Resistance (RON) for +2.7V Supply ■ FSA5157 Features Less than 12μA ICCT Current 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
Applications
■ Cellular Phone ■ PDA ■ Portable Media Player General Description The FSA5157 is a low on resistance, low-power, Single Pole Double Throw (SPDT) analog switch. This product has been designed for switching audio signals in applica- tions such as cell phones and portable media players. The ultra-low 0.4Ω impedance, sub-μA current consump- tion, 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. A growing number of applications require the voltage applied to the select input to be lower than the V CC applied. Under this condition, most switches would typi- cally consume over 100 μA 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 <12μA under a worst-case condition of VCC = 4.3V and VIN = 1.8V.

The device may not function or be opera- ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi- tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Note: 1. The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Recommended Operating Conditions The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild doe s not recommend exceeding them or designing to absolute maximum ratings. Note: 2. Unused inputs must be held HIGH or LOW. They may not float. Symbol Parameter Min.

On resistance is determined by the voltage drop between A and B pins at the indicated current through the switch. 4. ΔRON = RONmax − RONmin measured at identical VCC, temperature, and voltage. 5. Flatness is defined as the difference between the maximum and minimum value of on resistance over the specified range of conditions.
