Fairchild FSA5157P6X 0.4î© low-voltage spdt analog switch Datasheet

FSA5157
0.4Ω Low-Voltage SPDT Analog Switch
Features
General Description
■ Typical 0.4Ω On Resistance (RON) for +2.7V Supply
■ FSA5157 Features Less than 12μA ICCT Current
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 0.4Ω impedance, sub-μA 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.
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
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 100μA 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.
Applications
■ Cellular Phone
■ PDA
■ Portable Media Player

Pin Assignments
Stresses exceeding the absolute maximum ratings may damage the device. 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.

Notes:
3. 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.
