Low-Voltage, Dual DPDT/Quad SPDT Analog Switches in QFN

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 75Ω 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.
