UM4717/UM4717Q
4.5Ω 300MHz Bandwidth Dual SPDT Analog Switch
UM4717 CSP10 1.90×1.40
UM4717Q QFN10 1.80×1.40
General Description
The UM4717/UM4717Q low-voltage, low on-resistance (R_ON), dual single-pole/double-throw
(SPDT) analog switch operates from a single +1.8V to +5.5V supply. The device is designed for
USB 1.1/2.0 and audio switching applications.
The UM4717 features two 4.5Ω R_ON(max) SPDT switches with 1.2Ω flatness and 0.3Ω matching
between channels, while the UM4717Q features two 6Ω R_ON(max) SPDT switches with 1.8Ω
flatness and 0.6Ω matching between channels. The switch offers break-before-make switching
(1ns) with t_ON<80ns and t_OFF<40ns at +2.7V. The digital logic inputs are +1.8V logic compatible
with a +2.7V to +3.6V supply.
The UM4717 is packaged in a chip-scale package (CSP), occupies only a 1.90mm ×1.40mm area
and has a 4×3 bump array with a bump pitch of 0.50mm. The UM4717Q is packaged in a 1.80mm
×1.40mm QFN10 package, both significantly reducing the required PC board area.
