Analog Devices Inc./Maxim Integrated MAX4530EPP

Overview

The MAX4530EPP from Maxim Integrated is an 8-channel CMOS analog multiplexer with dual enable inputs, address latching, and rail-to-rail signal handling. It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, features 150Ω max on-resistance (±5V), 8Ω max channel matching, and 1nA COM-off leakage at +25°C. It is used in precision data acquisition systems requiring low-leakage, fast switching, and wide supply flexibility.

For engineers reviewing the MAX4530EPP datasheet, MAX4530EPP pinout, MAX4530EPP application, or MAX4530EPP equivalent, this page delivers verified electrical specs, package-confirmed pin functions, temperature-rated performance data (-40°C to +85°C), and real-world routing use cases for battery-powered test equipment and avionics signal conditioning.

Technical Context

The MAX4530EPP implements a single 8:1 analog mux architecture with three address bits (ADDA/ADDB/ADDC), two independent enable inputs (EN1/EN2), and a latch-enable (LE) that captures address states asynchronously. Its CMOS switch core uses matched P/N transistor pairs to achieve low R_ON flatness (13Ω typ) and minimal charge injection (1.5pC).

All digital inputs meet TTL/CMOS thresholds (0.8V low / 2.4V high) across its full supply range, and internal ESD protection exceeds 2kV per Method 3015.7. The device supports break-before-make timing (4ns min) and delivers 150ns t_ON/120ns t_OFF at ±4.5V, enabling reliable channel sequencing in multi-signal monitoring systems.

FAQ

What is the maximum supply voltage rating for MAX4530EPP?

The MAX4530EPP has an absolute maximum rating of +13V on V+ relative to V-, and ±20mA continuous current per terminal. For reliable operation, use within the recommended range: ±2V to ±6V dual supply or +2V to +12V single supply. Exceeding these limits risks permanent damage, especially if analog signals exceed V+ or fall below V- due to internal ESD diode conduction.

Does MAX4530EPP support true rail-to-rail analog signal switching?

Yes, the MAX4530EPP supports rail-to-rail analog signal handling: signals on COM and NOx pins can swing from V– to V+ without clipping or distortion. This is confirmed in the Electrical Characteristics table (Analog-Signal Range = V– to V+) and validated across ±4.5V, ±5V, and +5V supply conditions - enabling direct interfacing with op-amps and ADCs operating at full supply rails.

How does the dual-enable logic (EN1/EN2) function in MAX4530EPP?

In the MAX4530EPP, both EN1 and EN2 must be asserted simultaneously - EN1 low and EN2 high - to activate switching. If either enable is inactive, all channels remain open (high-impedance). This complementary arrangement provides hardware-level fault tolerance, preventing unintended channel closure during power-up, reset, or logic glitches - a key requirement in safety-critical ATE and avionics systems.

What is the purpose of the LE (Latch Enable) pin on MAX4530EPP?

The LE pin on MAX4530EPP captures and holds the state of ADDA/ADDB/ADDC address inputs on its rising edge, decoupling channel selection from real-time address bus stability. This allows microcontrollers to update address lines asynchronously and then trigger a clean, glitch-free channel change - essential for deterministic timing in synchronized data acquisition and avoids metastability in noisy industrial environments.

Can MAX4530EPP operate from a +3.3V single supply?

Yes, the MAX4530EPP operates from +2V to +12V single supply, including +3.3V. At +3.3V, R_ON increases to ~600Ω (typ), and switching times lengthen (t_ON/t_OFF ≈ 350ns), but logic thresholds remain compatible (0.8V/2.4V). For low-R_ON performance, use ≥+4.5V; for ultra-low power in battery systems, +3.3V operation is fully functional and characterized in the datasheet's Single +3V Supply section.
