UM5223
0.5Ω Ultra Low ON-Resistance Dual SPDT Analog Switch
UM5223
QFN10 1.8×1.4
General Description
The UM5223 is a low on-resistance (R
ON
), dual single-pole/double-throw (SPDT) analog switch
operates from a single +1.65V to +4.5V supply. The device’s targeted applications include battery
powered equipment that benefit from it’s low on-resistance.
The UM5223 features two 0.5Ω R
ON
(max) SPDT switches with 0.15Ω flatness and 0.05Ω
matching between channels. The switch offers break-before-make switching (1ns) with t
ON
< 60ns
and t
OFF
< 40ns at +2.7V.
The switch is available in Pb-free QFN10 package.
Applications
Cell Phone Audio Block
Speaker and Earphone Switching
Portable Instrumentation
Battery-Operated Equipment
Modems
Medical Equipment
Computer Peripherals
Ring-Tone Chip/Amplifier Switching
