The MAX4706/MAX4707 single-pole/single-throw (SPST) switches operate from a single 1.8V to 5.5V supply. The MAX4706 is a normally closed (NC) switch and the MAX4707 is the normally open (NO) version. These switches provide 2Ω on-resistance (R_ON) and 0.6Ω R_ON flatness with a +2.7V supply. These devices typically consume only 0.02µA of quiescent current, making them suitable for use in low-power, portable applications. The MAX4706/MAX4707 feature low-leakage 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.
