MAX4699ETE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4699ETE+ is a low-voltage, single-supply CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a dual double-pole/double-throw (DPDT) configuration with two control inputs managing two single-pole/double-throw (SPDT) switches each. The device operates from a +1.8V to +5.5V power supply and provides rail-to-rail signal handling. Key electrical parameters include a maximum on-resistance of 75Ω at +3V and 40Ω at +5V, with a maximum on-resistance flatness of 12Ω and channel matching of 4Ω. Switching speeds are characterized by a turn-on time of 35ns and a turn-off time of 20ns at +3V. The component offers a -3dB bandwidth of 250MHz, off-isolation of -76dB, and crosstalk of -79dB at 1MHz. Leakage current is limited to a maximum of 1nA at +85°C. It is housed in a 16-lead 4mm x 4mm TQFN package with an exposed pad.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix ETE+ to confirm the 16-lead TQFN-EP package and lead-free/RoHS compliance status. Ensure the exposed pad connection requirement is addressed in the PCB layout design. Confirm that the operating temperature range of -40°C to +85°C aligns with the intended application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual DPDT analog switch is required within a low-voltage single-supply system. It is suitable for applications demanding rail-to-rail signal transmission and fast switching speeds. Consider the 4mm x 4mm TQFN package dimensions for space-constrained designs. Verify logic input compatibility, as the MAX4699 requires a minimum +3V supply for 1.8V-logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4699ETE+ belongs to the MAX4699/MAX4701/MAX4702 family of low-voltage CMOS analog switches. While the MAX4699 and MAX4701 share the dual DPDT architecture, the MAX4702 differs by offering a quad SPDT configuration with a separate logic supply pin. This family is designed for portable and battery-powered applications requiring efficient signal path management.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the MAX4701EUE+ and MAX4701ETE+, which offer identical dual DPDT functionality but differ in package type (TSSOP vs. TQFN). Cross-family substitution requires careful evaluation of pinout compatibility and electrical parameter alignment.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic input compatibility for the MAX4699?

The MAX4699 digital inputs are 1.8V-logic compatible when operated from a +3V supply.

How does the MAX4699 handle overvoltage conditions?

Signals exceeding 0V or V+ are clamped by internal diodes. External blocking diodes can be added to protect against overvoltage if analog signals exceed the absolute maximum ratings.

What is the maximum power dissipation for the TQFN package?

The continuous power dissipation for the 16-Pin TQFN package is 1666.7mW at TA = +70°C, derating by 20.8mW/°C above +70°C.
