Allowing designs without ac coupling capacitance in audio applications, the AS1747 dual SPDT analog signal switch offers a negative signal capability. The switch combines an on-resistance of 0.4 Ω with a channel-to-channel matching of less then 0.03 Ω.
Additionally, the part features an on-resistance flatness of 0.25 Ω and a THD+N of 0.01% typ. The AS1747 operates from 1.8 to 5.5 V and is available in a 10-pin TDFN package suitable for operating environments ranging from –40° to 85°C. ($1.07 ea/1,000 — available now.)
