Descriptions
The DIO1269 is a high-performance, dual
Single-Pole Double-Throw (SPDT) analog switch
with negative swing audio capability. The DIO1269
features ultra-low RON of 1Ω (typical) at 3.0V VCC.
The DIO1269 operates over a wide VCC range of
2.7V to 5V, is fabricated with sub-micron CMOS
technology to achieve fast switching speeds, and
is designed for break-before-make operation. The
select input is TTL-level compatible.
The DIO1269 features very low quiescent current
even when the control voltage is lower than the
VCC supply. This feature suits mobile handset
applications by allowing direct interface with
baseband processor general-purpose I/Os with
minimal battery consumption.
