The MAX4719 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 MAX4719 features 20Ω R_ON (max) with 1.2Ω flatness and 0.4Ω 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 switch is packaged in a chip-scale package (UCSP™), significantly reducing the required PC board area. The chip occupies only a 2.0mm x 1.50mm area and has a 4 x 3 bump array with a bump pitch of 0.5mm. The MAX4719 is also available in a 10-pin µMAX® package.
