19-6389; Rev 0; 6/12 MAX14589E/MAX14594E High-Density, ±5V Capable DPDT Analog Switches General Description Benefits and Features The MAX14589E/MAX14594E high-density, double-pole/ double-throw (DPDT) analog switches feature Beyondthe-Rails™ 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 (0.2I) makes the devices ideal for low-distortion switching, such as audio. S Distortion-Free Beyond-the-Rails Signaling Negative Audio and Video Signal Capable -5.5V to +5.5V Analog Signal Range Independent from VCCEN On-Resistance 0.2I (typ) +1.6V to +5.5V Single-Supply Range Click-and-Pop Suppression 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. S Smooth Switch Transition Break-Before-Make Operation 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 highimpedance mode and all analog signal ports can withstand signals from -5.5V to +5.5V. The devices control the switches with a control bit, CB. S ESD Protection on COM_ ±15kV Human Body Model ±10kV IEC 61000-4-2 Air Gap ±8kV IEC 61000-4-2 Contact The MAX14589E/MAX14594E are available in a 1.2mm x 1.2mm, 0.4mm pitch, 9-bump wafer-level package (WLP), and operate over the -40NC to +85NC extended temperature range.

MAX14589E/MAX14594E High-Density, ±5V Capable DPDT Analog Switches Detailed Description sounds that might occur when switching between capacitively coupled audio sources. The MAX14589E/MAX14594E are low on-resistance and high ESD-protected DPDT switches that operate from a +1.6V to +5.5V supply and are designed to multiplex AC-coupled analog signals. These switches feature the low on-resistance (RON) necessary for highperformance switching applications. The Beyond-theRails signal capability of the analog channel allows signals below ground and above VCCEN to pass through without distortion....
