• Manufacturer Part Number: MAX14504
• 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
• Manufacturer: Maxim

The MAX14504/MAX14505/MAX14505A/MAX14506 are
low on-resistance, low-voltage, dual SPDT analog
switches that operate from a +2.3V to +5.5V single
supply. These devices feature a negative signal capa-
bility that allows signals as low as -V
without distortion.
The MAX14504/MAX14505/MAX14505A/MAX14506
have an enable input EN to put the switches in a high-

The MAX14505/MAX14505A have internal shunt switch-
es on both NO1 and NO2 terminals to suppress click-
