Analog Devices Inc./Maxim Integrated MAX4052CSE

Overview

MAX4052CSE from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It supports single-supply operation from +2.7V to +16V or dual supplies from ±2.7V to ±8V, delivers rail-to-rail analog switching, and features guaranteed 100Ω on-resistance (±5V), 12Ω channel-to-channel on-resistance match, and 0.1nA off-leakage at +25°C - enabling precision signal selection in battery-powered data acquisition.

For engineers reviewing the MAX4052CSE datasheet, MAX4052CSE pinout, MAX4052CSE application, or MAX4052CSE equivalent, key selection criteria include its dual 4:1 configuration, TTL/CMOS-compatible logic thresholds (0.8V–2.4V), low crosstalk (< –90dB), high off-isolation (< –90dB), and compatibility with industry-standard 74HC4052 footprint and control interface.

Technical Context

The MAX4052CSE implements two independent 4:1 analog multiplexers using matched CMOS transmission gates driven by address-decoded logic. Each section uses ADDA and ADDB inputs to select one of four NOx inputs to route to its COM terminal, with INH enabling global disable. The internal logic-level translators isolate digital control signals from analog supply domains (V+, V–, GND).

It operates across three supply configurations: bipolar (±2.7V to ±8V), single positive (+2.7V to +16V), or single-ended with V– tied to GND. Analog signal range spans rail-to-rail (V– to V+), and all NO/COM pins are bidirectional with identical electrical characteristics - no dedicated input/output assignment required.

FAQ

What supply configurations does the MAX4052CSE support?

The MAX4052CSE supports single-supply operation from +2.7V to +16V (with V– tied to GND) and dual-supply operation from ±2.7V to ±8V. It handles rail-to-rail analog signals across these ranges and maintains guaranteed on-resistance and leakage specs in both modes. The MAX4052CSE is not rated for asymmetric dual supplies exceeding ±8V total differential.

How does the MAX4052CSE handle bidirectional signal flow?

All NO and COM pins on the MAX4052CSE are electrically identical and fully bidirectional - signals pass with equal on-resistance and capacitance in either direction. This allows flexible routing where the same pin can serve as input or output depending on system architecture, eliminating need for directional design constraints in the MAX4052CSE layout.

What is the function of the INH pin on the MAX4052CSE?

The INH (Inhibit) pin on the MAX4052CSE is a digital active-high enable control. When pulled high, it forces all internal switches open regardless of address inputs - providing hardware-level channel isolation. When low or grounded, the MAX4052CSE responds normally to ADDA/ADDB for channel selection. This feature enables fail-safe shutdown in safety-critical systems.

Does the MAX4052CSE require external level-shifting for 3.3V microcontroller control?

No, the MAX4052CSE does not require external level-shifting when driven by 3.3V microcontrollers. Its logic thresholds (0.8V low, 2.4V high) are fully compatible with 3.3V CMOS outputs, and it operates reliably with V+ = +3.3V (single supply) or ±3.3V (dual supply). This simplifies interface design and reduces component count in the MAX4052CSE application.

What is the maximum analog signal frequency supported by the MAX4052CSE?

The MAX4052CSE maintains flat insertion loss up to 50MHz in 50Ω systems, with off-isolation remaining > –45dB at 10MHz. For high-fidelity audio (20Hz–20kHz), its < 0.04% THD and < –90dB crosstalk ensure transparent signal routing. At frequencies above 20MHz, layout-dependent peaking may occur, so the MAX4052CSE is best applied below 50MHz for predictable performance.
