Maxim Integrated Products introduces the MAX4908/MAX4909, dual SP3T (single-pole triple-throw) analog switches. These switches handle negative signals with a single positive power supply, thereby reducing external component count and improving audio signal quality. The MAX4908/MAX4909 feature integrated shunt resistors to ground. This feature reduces audio popping and clicking sounds by depleting the capacitive charge, which commonly builds up on the unconnected port of the switch, to ground. In addition, a 0.38Ω on-resistance, a 0.35Ω on-resistance flatness, and a 0.02% total harmonic distortion yield desirable audio signal quality.
