The MAX14504/MAX14505/MAX14505A/MAX14506 are dual single-pole/double-throw (SPDT) audio switches with 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. 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, 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.
The MAX14504, MAX14505, MAX14505A, and MAX14506 are dual single‑pole/double‑throw (SPDT) analog switches that support negative‑signal operation, allowing signals from -VCC to +VCC to pass without distortion. They operate from a single +2.3 V to +5.5 V supply and are offered in a 1.56 mm × 2.14 mm 12‑bump WLP package.
Key features include high continuous current ratings (550 mA continuous, 850 mA pulsed), low on‑resistance (0.36 Ω typ), internal shunt switches on the MAX14505/05A to suppress click‑and‑pop sounds, and operation over an extended temperature range of –40 °C to +85 °C. The devices provide an enable input (EN) for high‑impedance mode and a control bit (CB) for switching control.
