Analog Devices Inc./Maxim Integrated MAX4052CEE+T

Overview

MAX4052CEE+T from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional rail-to-rail signal routing in low-voltage systems. It supports ±2.7V to ±8V dual supplies or +2.7V to +16V single supply, delivers 100Ω typical on-resistance at ±5V, guarantees ≤12Ω channel-to-channel on-resistance match, and exhibits only 0.1nA max off-leakage at +25°C - enabling precision signal selection in battery-powered data acquisition.

For engineers reviewing the MAX4052CEE+T datasheet, MAX4052CEE+T pinout, MAX4052CEE+T application, or MAX4052CEE+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤10Ω), break-before-make timing (≤200ns), low crosstalk (<–90dB), high off-isolation (<–90dB), and TTL/CMOS logic compatibility across supply ranges.

Technical Context

The MAX4052CEE+T implements two independent 4:1 analog multiplexers using complementary CMOS switch architecture with integrated level translators. Each section uses three address inputs (ADDA, ADDB, INH) to select one of four NOx inputs to route to its COM terminal, with no internal decoding beyond binary selection logic.

It operates without ground reference for analog signals - all analog paths are bounded strictly between V+ and V− - and features ESD protection diodes from each NO/COM pin to both supply rails, defining absolute maximum analog voltage limits and contributing to leakage current behavior across temperature and signal voltage.

Key Specifications

Pinout & Package

FAQ

What supply voltage ranges does the MAX4052CEE+T support?

The MAX4052CEE+T supports dual supplies from ±2.7V to ±8V or a single supply from +2.7V to +16V. When using single-supply operation, V− must be tied to GND. The device maintains rail-to-rail analog signal handling across all supported supply configurations, and logic inputs remain TTL/CMOS-compatible throughout this range. The MAX4052CEE+T is rated for 0°C to +70°C operation.

How many analog channels does the MAX4052CEE+T provide, and how are they organized?

The MAX4052CEE+T integrates two independent 4:1 analog multiplexers - Section A (COMA with NO0A–NO3A) and Section B (COMB with NO0B–NO3B). Each section is controlled by shared ADDA/ADDB address lines and a common INH inhibit input. This dual-4:1 architecture allows simultaneous or independent routing of two separate analog signal streams, unlike 8:1 single-mux alternatives. The MAX4052CEE+T pinout reflects this structure with dedicated COM and NO pins for each section.

What is the maximum on-resistance and channel matching specification for the MAX4052CEE+T?

The MAX4052CEE+T guarantees a maximum on-resistance (RON) of 100Ω at ±5V supplies and 280Ω at +5V single supply. Its channel-to-channel on-resistance match is specified at ≤12Ω (ΔRON = RON_MAX − RON_MIN). These parameters are measured under defined conditions (INO = 1mA, VCOM = ±3V for dual supply) and directly impact gain consistency and signal fidelity in multi-channel measurement systems. The MAX4052CEE+T datasheet confirms these values across the commercial temperature range.

Does the MAX4052CEE+T require a ground connection for analog signals?

No - the MAX4052CEE+T does not require or use GND as an analog reference. Analog signals are fully differential between V+ and V−, with no internal connection to GND. The GND pin serves only as the reference for digital logic inputs (ADDA, ADDB, INH). This architecture enables true floating analog paths, critical for isolated sensor interfaces and systems where analog and digital grounds are separated. All analog leakage paths in the MAX4052CEE+T flow between NO/COM pins and V+/V−, not GND.

What is the purpose of the INH pin on the MAX4052CEE+T, and how should it be used?

INH (Inhibit) is an active-high digital input that globally disables all analog switches in the MAX4052CEE+T, forcing them into the open (high-impedance) state regardless of address inputs. It should be tied to GND during normal operation. During power-up sequencing, INH must be held low until V+ and V− are stable to prevent undefined switch states. In fault-tolerant designs, INH can be driven high by a watchdog or supervisor IC to isolate analog paths during system errors. This functionality is intrinsic to the MAX4052CEE+T's architecture and requires no external components.
