AS1749 - Audio Clickless Switches

Download the AS1749 datasheet PDF. This datasheet also covers the AS1748 variant, as both devices belong to the same audio clickless switches family and are provided as variant models within a single manufacturer datasheet.

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.
