MAX4719 Datasheet, PDF (1/11 Pages) Maxim Integrated Products – 300MHz Bandwidth, Dual SPDT Analog Switch in UCSP
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.
