MAX4702

19-2129; Rev 2; 10/09 Low-Voltage, Dual DPDT/Quad SPDT Analog Switches in QFN General Description The MAX4699/MAX4701/MAX4702 are low-voltage, single-supply CMOS analog switches. The MAX4699/ MAX4701 are dual double-pole/double-throw (DPDT) switches with two control inputs that control two single-pole/double-throw (SPDT) switches each. The MAX4702 is a quad SPDT switch with one control input and one low-voltage digital logic power supply. These devices operate from a single +1.8V to +5.5V power supply. When powered from a +2.7V supply the MAX4699/MAX4701/MAX4702 offer a 75 Ω on-resistance (RON), with 12Ω max RON flatness and 4Ω max matching between channels. Each switch has rail-to-rail signal handling, fast switching speeds of tON = 35ns, tOFF = 20ns, and a maximum 1nA of leakage current. The MAX4699/MAX4701 digital inputs are 1.8V-logic compatible when operated from a +3V supply. The MAX4702’s digital inputs feature a 1.0V threshold when powered with a 1.5V logic supply. The MAX4699 is available in a space-saving 16-lead 4mm x 4mm TQFN package. The MAX4701/MAX4702 are available in space-saving 16-lead 3mm x 3mm TQFN 16-pin TSSOP packages. ♦ Guaranteed On-Resistance: 75Ω (max) (+3V Supply) 40Ω (max) (+5V Supply) ♦ Guaranteed Match Between Channels: 4Ω max ♦ Guaranteed Flatness Over Signal Range: 12Ω max ♦ Low Leakage Currents Over Temperature: 1nA Max at +85°C ♦ Fast Switching: tON = 35ns, tOFF = 20ns ♦ Guaranteed Break-Before-Make ♦ Single-Supply Operation from +1.8V to +5...
