FSA5157 0.4Ω Low Voltage SPDT Analog Switch General Description Features 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. ■ 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) 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. ■ Control logic is 1.8V CMOS logic compatible Applications ■ Cellular phone ■ PDA ■ Portable Media Player Ordering Information Order Number Package Number Product Code Top Mark FSA5157P6X MAA06A C57 Pb-Free 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3K Units on Tape and Reel FSA5157L6X MAC06A FT Pb-Free 6-Lead MicroPak, 1.0mm Wide 5K Units on Tape and Reel Package Description Supplied As Pb-Free package per JEDEC J-STD-020B.
