4.5Ω/20Ω, 300MHz Bandwidth, Dual SPDT
Analog Switches in UCSP
General Description
The MAX4717/MAX4718 low-voltage, low on-resistance
(R_ON), dual single-pole/double throw (SPDT) analog
switches operate from a single +1.8V to +5.5V supply.
These devices are designed for USB 1.1 and audio
switching applications.
The MAX4717 features two 4.5Ω R_ON (max) SPDT
switches with 1.2Ω flatness and 0.3Ω matching between
channels. The MAX4718 features one 4.5Ω R_ON (max)
SPDT switch and one 20Ω R_ON (max) SPDT switch. The
20Ω switch has a guaranteed matching and flatness of
0.4Ω and 1.2Ω, respectively. These switches offer 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.
These switches are 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. These switches are also available in a 10-pin
µMAX package.
