AS1747 Low-Voltage Dual SPDT Audio Clickless Switch

The SPDT (single-pole/double-throw) switch AS1747 allows signals below ground to pass through without distortion. This analog switch is ideal for switching audio signals, due to the supply voltage from +1.8V to +5.5V and the low 0.4Ω on-resistance. This SPDT switch is available in space-saving 10-pi.
