Low Voltage SPDT Analog Switch

FSA5157 0.4Ω Low Voltage SPDT Analog Switch January 2007 FSA5157 0.4Ω Low Voltage SPDT Analog Switch 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 applications such as cell phones and portable media players. The ultra-low 0.4¾ impedance, sub 1μA 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 make-before-break 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 then 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 has been designed to minimize current consumption under this condition. The ICCT is specified for <12μA under a worse case condition of VCC = 4.3V and VIN = 1.8V. 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 ■ 1.0mm x 1.45mm 6-Lead Pb-Free 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 Ordering Information Order Number FSA5157P6X FSA5157L6X Package Number MAA06A MAC06A Product Code Top Mark C57 FT Package Description Pb-Free 6-Lead SC70, EIAJ SC88, 1.25mm Wide Pb-Free 6-Lead MicroPak, 1.0mm Wide Supplied As 3K Units on Tape and Reel 5K Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.

The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
