Low On Resistance (0.75Ω) Dual SPDT Analog
Switch with Negative Swing Audio Capability
WAS4729QB
Http//:www.sh-willsemi.com
Descriptions
The WAS4729QB is a high performance, dual
Single Pole Double Throw (SPDT) analog switch with
negative swing audio capability that features ultra-low
Ron of 0.75Ω (typical) at 3.6V VCC. The WAS4729QB
operates over a wide VCC range of 2.3V to 5.5V and is
designed for break-before-make operation. The select
input is TTL-level compatible.
WAS4729QB is also featured with smart circuitry
to minimize VCC leakage current even when the
control voltage is lower than VCC supply voltage. This
feature suits mobile handset applications by allowing
direct interface with baseband processor
general-purpose IO with minimal battery consumption.
In other word, there is no need of additional device to
shift control level to be the same as that of VCC in real
application.
The WAS4729QB is available in QFN1418-10L
package. Standard product is Pb-Free and
halogen-Free.
