MAX4717

19-2627; Rev 0; 10/02 4.5Ω/20Ω, 300MHz Bandwidth, Dual SPDT Analog Switches in UCSP General Description 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 4.5 Ω R ON (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 breakbefore-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 ✕ 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.
