MAX4685ETB+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4685ETB+T is a dual 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 maximum on-resistance of 0.8Ω for both normally open and normally closed switches at a +2.7V supply. The device provides rail-to-rail signal handling, low crosstalk (-68dB at 100kHz), and high off-isolation (-64dB at 100kHz). It incorporates break-before-make switching with a turn-on time of 50ns maximum and a turn-off time of 40ns maximum. Packaged in a 10-pin TDFN with an exposed pad, it supports -40°C to +85°C operating temperatures.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm the package type matches the required PCB footprint and ensure compliance with RoHS standards as indicated by the suffix. Check for specific assembly requirements related to the thermal profile during soldering to maintain reliability.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual-channel SPDT switch is required for low-voltage applications. Ensure the supply voltage falls within the 1.8V to 5.5V range. Consider the 0.8Ω on-resistance for signal integrity needs. Verify that the TDFN package dimensions fit the design constraints and that the logic input levels are compatible with the system's control signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4684/MAX4685 family of low on-resistance, low-voltage analog switches. It shares similar electrical characteristics with the MAX4684 but differs in on-resistance symmetry. Both parts utilize the UCSP or TDFN packaging for space-saving designs. The family is designed for portable electronics requiring efficient power management and signal switching capabilities.
