MAX4694ETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4694ETE+ is a quad single-pole double-throw (SPDT) analog switch manufactured by Analog Devices/Maxim Integrated. It operates from a single +2V to +11V supply and features rail-to-rail signal handling with low leakage current. The device supports 1.8V logic compatibility at +3V supplies and TTL compatibility at +5V. Key electrical parameters include an on-resistance of 70Ω max at +2.7V, 35Ω max at +5V, and 25Ω max at ±4.5V dual supplies. Leakage currents are typically 1nA, with off-isolation of -88dB and crosstalk of -90dB at 100kHz. It utilizes a 16-pin TQFN-EP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required package type and temperature range. Ensure compliance with RoHS standards as indicated by the '+' suffix. Cross-reference the datasheet revision to confirm pinout and electrical characteristics align with design requirements before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4694ETE+ for applications requiring four independent SPDT switches in a compact surface-mount package. Consider the single-supply voltage range and logic compatibility when designing the control interface. Evaluate the on-resistance and leakage specifications against the signal integrity requirements of the target application. Ensure adequate thermal management for the TQFN-EP package if power dissipation exceeds typical limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4694ETE+ belongs to the MAX4691–MAX4694 family of low-voltage CMOS analog switches. This series includes multiplexers and SPDT switches in various configurations. The ETE+ suffix denotes a 16-pin TQFN-EP package with lead-free/RoHS compliance and an operating temperature range of -40°C to +85°C. The family shares common architectural features but differs in channel count and configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements within the same family include other MAX469x variants with different channel counts. Verify pin compatibility and electrical specifications when substituting.
