FSA5157
0.4: Low Voltage SPDT Analog Switch (Preliminary)
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 applications such as cell
phones and portable media players. The ultra-low 0.4 Ohm
impedance, sub 1
P
A current consumption, and 1.65V to 4.3V
operating voltage range makes this product ideal for battery
power 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.
A growing number of applications require the voltage applied to
the select input to be lower then the V
CC
applied. Under this
condition, most switches would typically consume over 100
P
A
of current. This would be an unacceptable level for battery pow-
ered applications. The FSA5157 has been designed to minimize
current consumption under this condition. The I
CCT
is specified
for
12
P
A under a worse case condition of V
CC
= 4.3V and
V
IN
= 1.8V.
