The MAX14504/MAX14505/MAX14505A/MAX14506 dual single-pole/double-throw (SPDT) audio switches feature negative signal capability that allows signals from -V_CC to +V_CC to pass without distortion. They feature high continuous current ratings of 550mA (continuous) and 850mA (pulsed). These analog switches have low on-resistance, low supply current, and operate from a single +2.3V to +5.5V supply.

The MAX14505/MAX14505A have internal shunt switches that discharge the audio amplifier AC-coupling capacitance at the normally open (NO) terminals. This reduces click-and-pop sounds that occur when switching audio signals between precharged points. The MAX14504/MAX14505/MAX14505A/MAX14506 control the switches with control bit, CB, and feature an enable input, active-low EN, that place COM in a high-impedance mode.

The MAX14504/MAX14505/MAX14505A/MAX14506 are fully specified to operate from a single +2.3V to +5.5V power supply. These devices are available in a 1.56mm x 2.14mm, 12-bump WLP package, and operate over the -40°C to +85°C extended temperature range.
