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

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.

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.
