General Description
The UM2268/UM2268A is a dual, low-power single-pole/ double-throw (SPDT) analog switch that operates from a single +1.8V to +4.4V supply.
The UM2268/UM2268A features guaranteed on-resistance matching (0.04Ω TYP) between switches and guaranteed on resistance flatness over the signal range (0.08Ω TYP), as well as high off-isolation and low crosstalk. This ensures excellent linearity and low distortion when switching audio signals.
