Reduces Click and Pop and Provides Low RON in Only 1.2mm x 1.2mm
The MAX14589E/MAX14594E high-density, double-pole/double-throw (DPDT) analog switches feature Beyond-the-Rails™ signal capability that allows signals from -5.5V to +5.5V to pass without distortion even when the power supply is below the signal range. The low RON resistance (0.2Ω) makes the devices ideal for low-distortion switching, such as audio. The MAX14594E has internal shunt switches that discharge the audio amplifier AC-coupling capacitance at the normally open (NO1 and NO2) terminals. This feature reduces click-and-pop sounds that occur when switching audio signals between precharged points. The switches are fully specified to operate from a single +1.6V to +5.5V power supply. Because of the low supply current requirement, VCCEN can be provided by a GPIO. When the power is not applied, switches go to a high-impedance mode and all analog signal ports can withstand signals within the analog signal range. The devices control the switches with a control bit, CB. The MAX14589E/MAX14594E are available in a 1.2mm × 1.2mm, 0.4mm pitch, 9-bump wafer-level package (WLP) and operate over the -40°C to +85°C extended temperature range.
