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 applica-
tions such as cell phones and portable media players.
The ultra-low 0.4¾ impedance, sub 1μA current con-
sumption, and 1.65V to 4.3V operating voltage range
makes this product ideal for battery powered applica-
tions. The FSA5157 also features bi-directional opera-
tion 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 typi-
cally consume over 100μA of current. This would be an
unacceptable level for battery powered applications. The
FSA5157 has been designed to minimize current con-
sumption 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

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, 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.
