MAX4729/MAX4730 Low-Voltage 3.5, SPDT, CMOS Analog Switches General Description Features The MAX4729/MAX4730 single-pole/double-throw Low 3.5 R (+2.7V Supply) ON (SPDT) switches operate from a single supply ranging 0.45 R Flatness (+2.7V Supply) ON from +1.8V to +5.5V. These switches provide low 3.5 on-resistance (R ), as well as 0.45 R flatness with ON ON 0.05 R Match Between Channels (+2.7V ON a +2.7V supply. These devices typically consume only Supply) 1nA of supply current, making them ideal for use in low- Tiny SC70 and DFN Packages power, portable applications. The MAX4729/MAX4730 feature low-leakage currents over the extended temper- -3dB Bandwidth: 300MHz ature range, TTL/CMOS-compatible digital logic, and Low On-Capacitance: 19.5pF excellent AC characteristics. 0.036% Total Harmonic Distortion The MAX4729/MAX4730 are available in small 6-pin SC70 and 6-pin DFN packages. The MAX4729/ Low Supply Current: 1nA MAX4730 are offered in three pinout configurations to +1.8V to +5.5V Single-Supply Operation ease design. The MAX4729/MAX4730 are specified over the extended -40C to +85C temperature range.

Signals on IN exceeding GND are clamped by an internal diode. 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.
