FSA5157
0.4Ω Low Voltage SPDT Analog Switch
January 2007
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 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.
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.
Features
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
