19-2626; Rev 0; 10/02 20Ω, 300MHz Bandwidth, Dual SPDT Analog Switch in UCSP General Description The MAX4719 low-voltage, low on-resistance (RON), dual single-pole/double throw (SPDT) analog switch operates from a single +1.8V to +5.5V supply. The MAX4719 features 20Ω RON (max) with 1.2Ω flatness and 0.4Ω matching between channels. The switch offers break-before-make switching (1ns) with tON <80ns and tOFF <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 ✕ 1.50mm area and has a 4 ✕ 3 bump array with a bump pitch of 0.5mm. The MAX4719 is also available in a 10-pin µMAX package.
