Analog Devices Inc./Maxim Integrated MAX4582EGE

Overview

MAX4582EGE from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It supports ±2V to ±6V dual supplies or +2V to +12V single supply, delivers 80Ω on-resistance at ±5V, guarantees <1nA off-leakage at +25°C, and achieves <−96dB crosstalk in 50Ω systems - enabling precision audio/video switching and battery-powered data acquisition.

For engineers reviewing the MAX4582EGE datasheet, MAX4582EGE pinout, MAX4582EGE application, or MAX4582EGE equivalent, key selection criteria include guaranteed on-resistance matching between channels, rail-to-rail analog signal handling, TTL/CMOS logic compatibility at +5V, low distortion (<0.02% @ 600Ω), and automotive-grade temperature range (−40°C to +85°C).

Technical Context

The MAX4582EGE implements two independent 4:1 analog multiplexers with shared digital control inputs (A, B, ENABLE) and separate analog I/O banks (X0–X3/X and Y0–Y3/Y). Each channel features break-before-make switching (4–20ns), charge injection ≤5pC, and flat on-resistance over full analog signal range (±4.5V with ±5V supplies).

It uses standard CMOS transmission-gate architecture with internal ESD diodes clamping analog pins to VCC and VEE. Logic-level translators isolate digital control circuitry from analog supply domains, ensuring robust operation across supply voltages while maintaining TTL/CMOS input thresholds (0.8V/2.4V at +5V).

Key Specifications

Pinout & Package

MAX4582EGE is housed in a 16-pin QFN package with exposed pad (G1644-1), 3mm × 3mm footprint, 0.5mm pitch, and thermal pad connected to VCC for enhanced power dissipation.

FAQ

What is the maximum analog signal voltage range supported by the MAX4582EGE?

The MAX4582EGE supports rail-to-rail analog signals from VEE to VCC. With ±5V dual supplies, this yields a ±5V range; with +5V single supply (VEE = GND), it supports 0V to +5V. Absolute maximum ratings allow VEE as low as −6V and VCC as high as +13V, but analog swing remains bounded by the applied supply rails. The MAX4582EGE does not require external biasing for full-range operation.

Does the MAX4582EGE support bidirectional signal flow?

Yes, the MAX4582EGE supports fully bidirectional analog signal flow. Its CMOS transmission-gate architecture makes all analog pins (X0–X3, X, Y0–Y3, Y) functionally identical - either can serve as input or output depending on system configuration. This enables flexible routing in both source-to-load and load-to-source topologies without signal degradation or added complexity.

How does the MAX4582EGE handle power-supply sequencing?

The MAX4582EGE recommends powering VCC first, then VEE, followed by logic inputs and analog signals. Improper sequencing may cause latch-up or excessive leakage. When sequencing isn't feasible, external blocking diodes (D1, D2) can be added in series with VCC and VEE pins per Figure 1 in the datasheet. These diodes reduce analog swing by ~0.7V but preserve MAX4582EGE's low R_ON and leakage performance.

Is the MAX4582EGE pin-compatible with legacy industry-standard multiplexers?

Yes, the MAX4582EGE is pin-compatible with the 74HC4052 and MAX4052 in QFN-16 (G1644-1) package. It shares identical pinout, logic diagram, and truth table behavior - though electrical specs (e.g., lower R_ON, tighter matching, wider supply range) exceed those older parts. No PCB redesign is needed when upgrading from MAX4052ESE or 74HC4052N to MAX4582EGE.

What is the role of the exposed pad on the MAX4582EGE QFN package?

The exposed pad on the MAX4582EGE must be soldered and electrically connected to VCC. It serves as both a thermal dissipation path and an extension of the internal VCC plane, improving power handling and reducing junction temperature rise during sustained switching. Leaving it unconnected or grounding it violates the device's thermal and electrical specifications and may cause premature failure.
