General Description
The G3203 is a low on-resistance, dual SPDT (Sin-
gle-Pole/Double-Throw) analog switch that operates
from a 2.7V to 5.5V supply. The G3203 features a
0.9Ω (max) R
ON
for its NC switch and a 1Ω(max) R
ON
for its NO switch at a +2.7V supply. The device offers
an excellent ON-resistance matching, and low total
harmonic distortion (THD) performance. The device is
designed for fast switching speeds with the
break-before-make feature to prevent signal distortion
during the transferring of signal from one channel to
another. These features make this device suitable for
portable audio applications.
The G3203 is available in the WLCSP3X4-10,
WLCSP3X4-12 and TDFN3X3-10 package.
