AS1748 - Audio Clickless Switches

General Description

2 Key

Key Features

  • The SPDT (single-pole/double-throw) switches AS1747, AS1748, AS1749 and AS1750 allow signals below ground to pass through without distortion. These analog switches are ideal for switching audio signals, due to their supply voltage from +1.8V to +5.5V and their low 0.4Ω on-resistance. An included comparator offers the AS1748 and AS1750 with headphone detection or mute/send key function. To reduce click-and-pop sounds when switching between pre-charged points the AS1749 and AS1750 have an interna.
