Low-Voltage, 60Ω, 4:1 Analog Multiplexer in QFN
General Description
The MAX4704 low-voltage, 4-channel analog multiplexer operates from a single +1.8V to +5.5V supply. The MAX4704 features break-before-make switching action with a tON = 60ns and tOFF = 20ns at +3V. When powered from a +2.7V supply, the device has a 60Ω (max) on-resistance (RON), with 3Ω (max) RON matching and 5Ω max RON flatness. The digital logic inputs are 1.8V-logic compatible from a +2.7V to +3.3V supply. The MAX4704 is available in both a space-saving 12-pin QFN (3mm x 3mm) package and a 10-pin µMAX package. o 3mm x 3mm 12-Pin QFN Package o Guaranteed On-Resistance: 60Ω (max) (+2.7V supply) 40Ω (max) (+5V supply) o Guaranteed Match Between Channels: 3Ω (max) o Guaranteed Flatness Over Signal Range: 5Ω (max) o Guaranteed Low Leakage Currents: 100pA (max) at +25°C o Switching Time: tON = 60ns, tOFF = 20ns o +1.8V to +5.5V Single-Supply Operation o Rail-to-Rail® Signal Handling o -3dB Bandwidth: >200MHz o Low Crosstalk: -90dB (1MHz) o High Off-Isolation: -85dB (1MHz) o Low 3pC Charge Injection o THD: 0.02% o +1.8V CMOS-Logic Compatible

Note 1: Signals on INH, ADD_, NO_, and COM exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
