| FSA5157 0.4: Low Voltage SPDT Analog Switch (Preliminary) November 2005 Revised November 2005 FSA5157 0.4: Low Voltage SPDT Analog Switch (Preliminary) 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 0.4 Ohm impedance, sub 1PA current consumption, and 1.65V to 4.3V operating voltage range makes this product ideal for battery power 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 100PA 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 12PA under a worse case condition of VCC = 4.3V and VIN = 1.8V. Features O Typical 0.4: On Resistance (RON) for 2.7V supply O FSA5157 features less than 12PA ICCT current when S input is lower than VCC O 0.25: maximum RON flatness for 2.7V supply O 1.0mm x 1.45mm 6-Lead Pb-Free MicroPak package O Broad VCC operating range: 1.65V to 4.3V O Low THD (0.02% typical for 32: load) O High current handling capability (350mA continuous current under 3.3V supply) O Control logic is 1.8V CMOS logic compatible Applications O Cellular phone O PDA O Portable Media Player Ordering Code: Product Order Number FSA5157P6X FSA5157P6X_NL FSA5157L6X Package Number MAA06A MAA06A MAC06A Code Top Mark A57 A57 FT Package Description Supplied As 6-Lead SC70, EIAJ SC88, 1.25mm Wide 3K Units on Tape and Reel Pb-Free 6-Lead SC70, EIAJ SC88, 1.25mm Wide Pb-Free 6-Lead MicroPak, 1.0mm Wide 3K Units on Tape and Reel 5K Units on Tape and Reel Pb-Free package per JEDEC J-STD-020B.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation. Note 2: The input and output negative voltage ratings may be exceeded if the input and output diode current ratings are observed. Note 3: Unused inputs must be held HIGH or LOW. They may not float.
