The MAX4699/MAX4701/MAX4702 are low-voltage, single-supply CMOS analog switches. MAX4699/MAX4701 are dual double-pole/double-throw (DPDT) switches with two control inputs that control two single-pole/double-throw (SPDT) switches each. 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-resis-tance (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. When operated from a +3V supply, the MAX4699/MAX4701 digital inputs are 1.8V-logic compatible. 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. Applications: Audio and Video Signal Routing, Cellular Phones, Battery-Operated Equipment, Communications Circuits, Modems.
The MAX4699, MAX4701, and MAX4702 are low‑voltage CMOS analog switches that operate from a single +1.8 V to +5.5 V supply. MAX4699 and MAX4701 provide dual double‑pole/double‑throw (DPDT) switching, while MAX4702 offers a quad single‑pole/double‑throw (SPDT) configuration. Typical applications include audio/video signal routing, cellular phones, battery‑operated equipment, communications circuits, and modems.
Key electrical characteristics include a guaranteed on‑resistance of 75 Ω at a +2.7 V supply, fast switching times of 35 ns (turn‑on) and 20 ns (turn‑off), leakage currents no greater than 1 nA, a -3 dB bandwidth of 250 MHz, crosstalk of –79 dB at 1 MHz, and off‑isolation of –76 dB at 1 MHz. The devices are offered in space‑saving 16‑lead TQFN (4 mm × 4 mm) and TSSOP (3 mm × 3 mm) packages.
