UM2268/UM2268A
0.4Ω Ultra Low ON-Resistance, Dual, SPDT Analog Switch
UM2268 QFN10 1.8×1.4
UM2268A QFN10 2.1×1.6
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.
The UM2268 is available in Pb-free QFN10 package (1.8mm×1.4mm×0.55mm), while the
UM2268A is available in Pb-free QFN10 package (2.1mm×1.6mm×0.55mm).
