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
