| FSA5157 -- 0.4 Low-Voltage SPDT Analog Switch February 2008 FSA5157 0.4 Low-Voltage SPDT Analog Switch Features Typical 0.4 On Resistance (RON) for +2.7V Supply FSA5157 Features Less than 12A ICCT Current 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 impedance, sub-A 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. 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 100A 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 <12A under a worst-case condition of VCC = 4.3V and VIN = 1.8V. When S Input is Lower than VCC 0.25 Maximum RON Flatness for +2.7V Supply 1.0 x 1.45mm 6-Lead MicroPakTM Package Broad VCC Operating Range: 1.65V to 4.3V Low THD (0.02% Typical for 32 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 Top Mark C57 FT Package Description 6-Lead SC70, EIAJ SC88, 1.25mm Wide 6-Lead MicroPak, 1.0mm Wide Packing Method 3000 Units on Tape and Reel 5000 Units on Tape and Reel All packages are lead free per JEDEC: J-STD-020B standard.
