WAS4729QB WAS4729QB Low On Resistance (0.8Ω) Dual SPDT Analog Switch with Negative Swing Audio Capability 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 0.8Ω (typical) at 3.6V VCC. The WAS4729QB QFN1418-10L 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 WAS4729QB interface with baseband processor general-purpose IO with minimal battery consumption. In other word, there QB is no need of additional device to shift control level to * = Month (A~Z) be the same as that of VCC in real application. Marking The WAS4729QB is available in QFN1418-10L package. Standard product is Pb-Free = Device code and halogen-Free.

These analog switches operate from a signal +2.3V to 5.5V supply. The input/output signal swing of device is dependent of the supply voltage V+: the device pass signals as high as V+ and as low as V+ - 6.5, including signals below ground with minimal distortion. Table 1 shows the input/output signal swing the user can get with different supply voltages. Min. Max.
