Low-Voltage, Dual DPDT/Quad SPDT Analog Switches in QFN
General Description
T h e MAX4699/MAX4701/MAX4702 are low-voltage, single-supply CMOS analog switches. The MAX4699/ MAX4701 are dual double-pole/double-throw (DPDT) s w i t c h e s 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 M A X 4 6 9 9 / M A X 4 7 0 1 / M A X 4 7 0 2 offer a 75 o n - r e s i s tance (RON), with 12 max RON flatness and 4 max matching between channels. Each switch has Rail-toRail® 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 c o m p a t i b l e 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 QFN package. The MAX4701/MAX4702 are available in space-saving 16-lead 3mm x 3mm QFN and 16-pin TSSOP packages.

Note 1: Signals on IN_, COM_, NO_, and NC_ exceeding 0 or V+ 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.
