WAS4729QB - Dual SPDT Analog Switch

General Description

The WAS4729QB is a high performance, dual Single Pole Double Throw (SPDT) analog switch with negative swing audio capability that

Key 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.

WAS4729QB 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.
