MAX4737/MAX4738/MAX4739 is a low voltage, low on-resistance (RON) quad single-pole/single throw (SPST) analog switch operating from a single +1.8V to +5.5V supply. These devices are designed for USB 1.1 and audio switching applications. The MAX4737/MAX4738/MAX4739 feature 4.5Ω RON (max) with 1.2Ω flatness and 0.4Ω 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 2mm ✕ 2mm area and has a 4 ✕ 4 bump array with a bump pitch of 0.5mm. These switches are also available in a 14-pin TSSOP package.
The MAX4737/MAX4738/MAX4739 are low-voltage, low on-resistance (RON), quad SPST analog switches designed for USB 1.1 and audio switching applications. These devices operate from a single +1.8V to +5.5V supply and feature guaranteed operation across this range.
The switches offer break-before-make switching with fast transition times and are available in a chip-scale package (UCSP) or a 14-pin TSSOP package. They are suitable for battery-operated equipment, audio/video signal routing, low-voltage data-acquisition systems, sample-and-hold circuits, communications circuits, and other applications requiring precise analog switching.
