Description
General part information
MAX4738 Series
The MAX4737/MAX4738/MAX4739 low-voltage, low on-resistance (RON), quad 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 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 x 2mm area and has a 4 x 4 bump array with a bump pitch of 0.5mm. These switches are also available in a 14-pin TSSOP package.ApplicationsAudio/Video Signal RoutingBattery-Operated EquipmentCommunications CircuitsData Acquisition SystemsLow-Voltage Data-Acquisition SystemsSample-and-Hold Circuits
