MAX14504 - Dual SPDT Negative Rail Analog Switches

General Description

The MAX14504/MAX14505/MAX14505A/MAX14506 dual single-pole/double-throw (SPDT) audio switches feature negative signal capability that allows signals from -VCC to +VCC to pass without distortion.

They feature high continuous current ratings of 550mA (continuous) and 850mA (pulsed).

MAX14504/MAX14505/MAX14505A/MAX14506 19-4244; Rev 1; 12/08 EVAALVUAAILTAIOBNLEKIT Dual SPDT Negative Rail Analog Switches with ±VCC Capability General Description The MAX14504/MAX14505/MAX14505A/MAX14506 dual single-pole/double-throw (SPDT) audio switches feature negative signal capability that allows signals from -VCC to +VCC 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.
