Analog Devices Inc./Maxim Integrated MAX4582ETE+

Overview

MAX4582ETE+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, delivers rail-to-rail analog switching, guarantees 80Ω on-resistance with ±5V supplies, and maintains <1nA off-leakage at +25°C - enabling precision signal selection in battery-powered audio routing and automotive sensor interfaces.

For engineers reviewing the MAX4582ETE+ datasheet, MAX4582ETE+ pinout, MAX4582ETE+ application, or MAX4582ETE+ equivalent, key selection criteria include guaranteed on-resistance matching between channels, -96dB crosstalk at 50Ω, high off-isolation (-74dB), break-before-make timing (4–20ns), and AEC-Q100 qualification for automotive temperature range (-40°C to +125°C).

Technical Context

The MAX4582ETE+ implements two independent 4:1 analog multiplexers sharing common address inputs (A, B) and enable control. Each channel uses complementary CMOS switch architecture with matched P- and N-channel transistors to achieve rail-to-rail signal handling and low distortion (<0.02% at 600Ω). Internal logic-level translators ensure TTL/CMOS compatibility across supply voltages.

Its dual-mux topology supports simultaneous selection of two independent analog paths - e.g., X0–X3 to X output and Y0–Y3 to Y output - with identical electrical performance per channel. Break-before-make switching prevents momentary shorting during address transitions, critical for avoiding signal glitches in data acquisition systems.

Key Specifications

FAQ

What supply voltage ranges does the MAX4582ETE+ support?

The MAX4582ETE+ supports dual supplies from ±2V to ±6V and single supplies from +2V to +12V. With ±5V supplies, it guarantees 80Ω on-resistance and <1nA off-leakage at +25°C. When operated from a +5V single supply (VEE = GND), on-resistance increases to 150Ω - a trade-off accepted for simplified power architecture in portable designs. The device remains functional down to +1.7V, though RON and timing degrade significantly below +2V.

Is the MAX4582ETE+ pin-compatible with industry-standard analog multiplexers?

Yes, the MAX4582ETE+ is pin-compatible with the 74HC4052 and MAX4052, sharing identical pinout, logic diagram, and functional behavior. This allows drop-in replacement in existing designs using those parts. However, the MAX4582ETE+ improves upon them with lower leakage (1nA vs. typical 10nA), tighter RON matching (≤10Ω vs. ~20Ω), and AEC-Q100 qualification - making it suitable for upgraded automotive and precision applications without layout changes.

How does the MAX4582ETE+ handle analog signal directionality?

The MAX4582ETE+ supports fully bidirectional analog signal flow: any X0–X3 or Y0–Y3 pin may serve as input or output, and signals pass equally well in both directions. This is enabled by its symmetrical CMOS switch structure and absence of internal diode biasing. The X and Y pins function as common terminals, while all eight channel pins are electrically identical - simplifying PCB routing and enabling flexible signal path design in both source- and sink-oriented architectures.

What is the significance of the exposed pad (EP) on the MAX4582ETE+ TQFN package?

The exposed pad (Pin 12) on the MAX4582ETE+ TQFN package must be soldered directly to the VCC plane on the PCB. Unlike standard thermal pads tied to GND, this pad connects internally to VCC to reduce power-supply impedance and improve high-frequency noise rejection. Proper connection lowers thermal resistance by ~30°C/W and enhances PSRR - critical for maintaining low THD and crosstalk in sensitive analog routing applications. Omitting this connection degrades thermal performance and may cause parametric shifts under load.

Does the MAX4582ETE+ require external protection diodes for overvoltage conditions?

No, the MAX4582ETE+ integrates reverse ESD-protection diodes between each analog pin and both VCC and VEE, eliminating the need for external diodes in most cases. However, if analog signals may exceed VCC or fall below VEE by more than 0.3V - such as in hot-plug or fault scenarios - external series diodes (e.g., 1N4148) should be added at VCC/VEE pins to clamp excursion and prevent latch-up. This configuration reduces analog signal range by ~0.7V but preserves the MAX4582ETE+'s low-leakage and low-RON characteristics.
