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
When S Input is Lower than VCC
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 0.4Ω impedance, sub-μA current consump-
tion, 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.
■ 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 typi-
cally consume over 100μA of current. This would be an
unacceptable level for battery-powered applications. The
FSA5157 is designed to minimize current consumption
Applications
■ Cellular Phone
■ PDA
■ Portable Media Player
under this condition. The ICCT is specified for
<12μA under
a worst-case condition of VCC = 4.3V and VIN = 1.8V

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.
