MAX4948ETG+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4948ETG+ is a hex single-pole/double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +5.5V supply and features a typical on-resistance of 4Ω and low capacitance of 30pF. The device includes one control logic input and an enable input (EN) to disable switches. Key electrical parameters include a power-supply range of 1.8V to 5.5V, -3dB bandwidth of 300MHz, and off-isolation of -70dB at 1MHz. It supports rail-to-rail signal handling and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking and package integrity against official specifications. Ensure the ordering suffix matches the required TQFN-EP package type. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a compact hex SPDT switch with low insertion loss is required. Consider the 24-pin TQFN package for space-constrained designs. Verify that the operating voltage range aligns with the system's power supply rails and that the thermal performance meets the application's requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4948ETG+ belongs to the MAX4947/MAX4948 family of analog switches. It is designed for high-speed data switching applications requiring low capacitance and on-resistance. The ETG+ suffix indicates a 24-pin TQFN package with lead-free construction, suitable for surface-mount assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4947ERA+ is a related part within the same family but offers a triple DPDT configuration instead of hex SPDT. Direct replacement requires verifying pin compatibility and functional equivalence for the specific application requirements.
