The MAX4706/MAX4707 are single-pole single-throw (SPST) switches that operate from a single 1.8V to 5.5V sup- ply. The MAX4706 is a normally closed (NC) switch and the MAX4707 is the normally open (NO) version. These switches provide 2Ω on-resistance (RON) and 0.6Ω RON flatness with a +2.7V supply. These devices typi- cally consume only 0.02µA of quiescent current, mak- ing them suitable for use in low-power, portable applications. The MAX4706/MAX4707 feature low-leak- age currents over the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. The MAX4706/MAX4707 are offered in small 5-pin and 6-pin SC70 and 6-pin µDFN packages. Applications include battery-operated equipment, audio signal routing, low-voltage data-acquisition systems, sample-and-hold circuits, communications circuits, and relay replacement.
The MAX4706 and MAX4707 are single‑pole/single‑throw (SPST) CMOS analog switches that operate from a single 1.8 V to 5.5 V supply. The MAX4706 is normally closed (NC) while the MAX4707 is normally open (NO). They are intended for low‑power, portable applications such as battery‑operated equipment, audio signal routing, and data‑acquisition systems.
Key electrical characteristics include a guaranteed on‑resistance of 2 Ω (max) at a 2.7 V supply, off‑isolation of –67 dB at 1 MHz, a –3 dB bandwidth of 190 MHz, and a total harmonic distortion of 0.013 %. The devices are offered in 5‑pin and 6‑pin SC70 packages as well as 6‑pin µDFN packages, and operate over –40 °C to +85 °C.
