The MAX4717/MAX4718 low-voltage, low on-resistance (RON), 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 RON (max) SPDT switches with 1.2Ω flatness and 0.3Ω matching between channels. The MAX4718 features one 4.5Ω RON (max) SPDT switch and one 20Ω RON (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 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 2.0mm x 1.50mm area and has a 4 x 3 bump array with a bump pitch of 0.5mm. These switches are also available in a 10-pin µMAX® package.
