0.65Ω DUAL SPDT ANALOG SWITCHES WITH NEGATIVE SIGNALING CAPABILITY

DESCRIPTION

The UTC UDS22364 is single-pole double-throw (SPDT) analog
switches designed to operate from 2.3V to 5.5V. The devices
feature negative signal capability that allows signals below ground
to pass through the switch without distortion. Additionally, the UTC
UDS22364 includes an internal shunt switch, which automatically
discharges any capacitance at the NC or NO terminals when they
are unconnected to COM. This reduces the audible click/pop noise
when switching between two sources. The break-before-make
feature prevents signal distortion during the transferring of a signal
from one path to another. Low ON-state resistance, excellent
channel-to-channel ON-state resistance matching, and minimal
total harmonic distortion (THD) performance are ideal for audio
applications.
