UM2268

UM2268 0.4Ω Ultra Low ON-Resistance, Dual, SPDT Analog Switch UM2268 QFN10 1.8×1.4 General Description The UM2268 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 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. The UM2268 is available in Pb-free QFN10 package (1.8mm×1.4mm×0.55mm).
