General Description

The MAX4719 low-voltage, low on-resistance (R

dual single-pole/double throw (SPDT) analog switch

operates from a single +1.8V to +5.5V supply. The

MAX4719 features 20Ω R

(max) with 1.2Ω flatness

and 0.4Ω matching between channels. The switch offers

break-before-make switching (1ns) with t

<80ns and

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 ✕ 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.

MAX4719 20Ω, 300MHz Bandwidth, Dual SPDT Analog Switch in UCSP Power-Supply Sequencing and Overvoltage Protection Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the device. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current-limited.
