MAX4729EXT

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4729EXT+T is a single-pole/double-throw (SPDT) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from +1.8V to +5.5V and features a low on-resistance of 3.5Ω at a +2.7V supply. The device provides excellent AC characteristics, including a -3dB bandwidth of 300MHz and total harmonic distortion of 0.036%. It consumes only 1nA of typical supply current, making it suitable for low-power applications. The component is housed in a 6-pin SC70 package and is specified over an extended temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing low-voltage, portable systems requiring minimal power consumption. The SPDT configuration allows for flexible signal routing between two paths. Consider the 3.5Ω on-resistance and 300MHz bandwidth for high-frequency signal applications. Verify compatibility with TTL/CMOS logic levels for digital control inputs across the operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4729EXT+T belongs to the MAX4729/MAX4730 family of low-voltage analog switches. This family is designed for applications where space and power are critical constraints. The MAX4729 variant offers specific pinout configurations compared to the MAX4730 to ease design implementation. Both variants share similar electrical characteristics but differ in internal channel connections.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same family include the MAX4730EXT+T, which shares the SC70 package and electrical performance but has a different pinout configuration. Designers must verify pin compatibility before substitution. Other low-voltage SPDT switches may require significant circuit redesign due to differences in on-resistance, leakage current, or package dimensions.
