4.5Ω/20Ω, 300MHz Bandwidth, Dual SPDT

Analog Switches in UCSP

General Description Features

The MAX4717/MAX4718 low-voltage, low on-resistance USB 1.1 Signal Switching Compliant (RON), dual single-pole/double throw (SPDT) analog (TID = 4000231)

switches operate from a single +1.8V to +5.5V supply. 2ns (max) Differential Skew These devices are designed for USB 1.1 and audio

-3d B Bandwidth: > 300MHz

switching applications.

Low 15p F On-Channel Capacitance

The MAX4717 features two 4.5Ω RON (max) SPDT

Single-Supply Operation from +1.8V to +5.5V

switches with 1.2Ω flatness and 0.3Ω matching between

channels. The MAX4718 features one 4.5Ω RON (max) 4.5Ω RON (max) Switches (MAX4717/MAX4718) SPDT switch and one 20Ω RON (max) SPDT switch. The 0.3Ω (max) RON Match (+3.0V Supply) 20Ω switch has a guaranteed matching and flatness of 1.2Ω (max) Flatness (+3.0V Supply)

0.4Ω and 1.2Ω, respectively. These switches offer break- 20Ω RON (max) Switch (MAX4718) before-make switching (1ns) with t ON <80ns and t OFF 0.4Ω (max) RON Match (+3.0V Supply) <40ns at +2.7V. The digital logic inputs are +1.8V logic 1.2Ω (max) Flatness (+3.0V Supply) compatible with a +2.7V to +3.6V supply.

Rail-to-Rail Signal Handling

These switches are packaged in a chip-scale package

High Off-Isolation: -55d B (10MHz)

(UCSP™), significantly reducing the required PC board

Low Crosstalk: -80d B (10MHz)

area. The chip occupies only a 2.0mm ✕ 1.50mm area

Low Distortion: 0.03%

and has a 4 ✕ 3 bump array with a bump pitch of 0.5mm. These switches are also available in 10-pin µMAX® and +1.8V CMOS-Logic Compatible 10-pin TDFN packages.
