The MAX4721/MAX4722/MAX4723 low-voltage, low on-resistance (RON), dual single-pole/single throw (SPST) 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 MAX4721/MAX4722/MAX4723 feature 4.5Ω RON (max) with 1.2Ω flatness and 0.3Ω matching between channels. These new switches feature guaranteed operation from +1.8V to +5.5V and are fully specified at 3V and 5V. These switches offer 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.
These switches are packaged in a chip-scale package (UCSP™), significantly reducing the required PC board area. The chip occupies only a 1.52mm x 1.52mm area and has a 3 x 3 bump array with a bump pitch of 0.5mm. These switches are also available in an 8-pin µMAX® package.
