MAX4729EXT-T

19-3284; Rev 1; 2/05 Low-Voltage 3.5Ω, SPDT, CMOS Analog Switches Features The MAX4729/MAX4730 single-pole/double-throw (SPDT) switches operate from a single supply ranging from +1.8V to +5.5V. These switches provide low 3.5Ω on-resistance (RON), as well as 0.45Ω RON flatness with a +2.7V supply. These devices typically consume only 1nA of supply current, making them ideal for use in lowpower, portable applications. The MAX4729/MAX4730 feature low-leakage currents over the extended temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. ♦ Low 3.5Ω RON (+2.7V Supply) The MAX4729/MAX4730 are available in small 6-pin SC70 and 6-pin µDFN packages. The MAX4729/ MAX4730 are offered in three pinout configurations to ease design. The MAX4729/MAX4730 are specified over the extended -40°C to +85°C temperature range. ♦ 0.036% Total Harmonic Distortion ♦ 0.45Ω RON Flatness (+2.7V Supply) ♦ 0.05Ω RON Match Between Channels (+2.7V Supply) ♦ Tiny SC70 and µDFN Packages ♦ -3dB Bandwidth: 300MHz ♦ Low On-Capacitance: 19.5pF ♦ Low Supply Current: 1nA ♦ +1.8V to +5.5V Single-Supply Operation Applications Ordering Information Battery-Operated Equipment PART TEMP RANGE MAX4729EXT-T -40ºC to +85ºC PINPACKAGE 6 SC70-6 MAX4729ELT-T* -40ºC to +85ºC 6 µDFN-6 — MAX4730EXT-T -40ºC to +85ºC 6 SC70-6 ABV MAX4730ELT-T* -40ºC to +85ºC 6 µDFN-6 — Audio and Video-Signal Routing Low-Voltage Data-Acquisition Systems Sample-and-Hold Circuits Communications Circuits Relay Replacement TOP MARK ABU *Future product—contact factory for availability.

The MAX4729/ MAX4730 feature low-leakage currents over the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. Applications Information supply, IN can be driven low to GND and high to +5.5V, allowing for mixing of logic levels in a system. With a 2.7V to 3.6V power-supply voltage range, the logic thresholds are set so VIL = 0.4V (max) and VIH = 2V (min). Power-Supply Sequencing and Overvoltage Protection Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the device. Proper power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current limited. Digital Control Inputs The MAX4729/MAX4730 logic inputs accept up to +5.5V, regardless of supply voltage.
