MAX4761EWX+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4761EWX+T is an octal 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 eight low-capacitance switches with a typical on-resistance of 2.0 Ω. The device includes one logic control input and an active-low enable input (EN). Key electrical parameters include a -3dB bandwidth of 150 MHz, off-isolation of 80 dB at 100 kHz, crosstalk of 95 dB at 100 kHz, and total harmonic distortion of 0.03%. It supports continuous current up to ±100 mA and peak pulsed current up to ±300 mA. The component is housed in a 36-bump UCSP package measuring 3mm x 3mm and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and logic threshold variations. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and any updates to absolute maximum ratings before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing circuits requiring multiple SPDT switches in a compact form factor. The UCSP package is suitable for space-constrained portable devices. Consider the logic threshold differences between standard and 'A' variants if interfacing with mixed-voltage logic systems. Verify that the required on-resistance flatness and channel matching meet the specific signal integrity requirements of the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4760/MAX4761 family of high-bandwidth analog switches. While the MAX4760 provides quad DPDT configuration, the MAX4761 variant offers octal SPDT functionality. Both share similar electrical characteristics and packaging options, allowing for flexible design choices based on the number of channels and pole/throw requirements needed for the system architecture.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4761ETX+T serves as a direct replacement offering identical SPDT functionality but utilizes a TQFN package instead of the UCSP format. Designers must account for the physical footprint difference and adjust PCB land patterns accordingly when substituting between these package types.
