Analog Devices Inc./Maxim Integrated MAX4052CEE+

Overview

MAX4052CEE+ 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), 6Ω channel-to-channel on-resistance match (A-suffix), and 0.1nA off-leakage at +25°C - enabling precision signal selection in battery-powered data acquisition.

For engineers reviewing the MAX4052CEE+ datasheet, MAX4052CEE+ pinout, MAX4052CEE+ application, or MAX4052CEE+ equivalent, key selection criteria include guaranteed on-resistance flatness, low charge injection (<10pC), high off-isolation (<–90dB), TTL/CMOS logic compatibility, and dual-4-channel architecture with independent address control.

Technical Context

The MAX4052CEE+ implements two independent 4:1 analog multiplexers sharing common digital control lines (ADDA, ADDB, INH) but operating on separate analog channel sets (COMA/NO0A–NO3A and COMB/NO0B–NO3B). Each switch uses complementary CMOS transmission gates with matched P/N device sizing to minimize on-resistance variation across VCOM.

Its logic interface accepts 0.8V–2.4V thresholds for robust TTL/CMOS compatibility across supply voltages; internal level translators drive analog switches directly from V+ and V−, isolating logic and analog domains. Break-before-make timing (≤200ns) prevents momentary shorting during channel transitions.

Key Specifications

Pinout & Package

MAX4052CEE+ is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch and standard JEDEC MO-137AC outline. The package is RoHS-compliant and rated for 0°C to +70°C operation.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power management ICs for demanding industrial, medical, and communications applications.

The MAX405x family targets low-voltage, low-leakage analog signal routing where rail-to-rail performance, guaranteed matching, and logic compatibility are critical - especially in portable and high-channel-count measurement systems.

FAQ

What is the maximum analog signal voltage range supported by the MAX4052CEE+?

The MAX4052CEE+ supports rail-to-rail analog signals between V− and V+. With ±5V supplies, this yields a ±5V range; with +5V/V− = GND, it supports 0V to +5V. Absolute maximum analog voltage is limited by V+ ≤ +17V and V− ≥ −17V, and signals must stay within (V− − 2V) to (V+ + 2V) to avoid forward-biasing internal ESD diodes. The MAX4052CEE+ does not require signal grounding.

Does the MAX4052CEE+ require external pull-up or pull-down resistors on its address pins?

No, the MAX4052CEE+ does not require external pull-up or pull-down resistors on ADDA, ADDB, or INH. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) and accept clean logic levels directly from microcontrollers or FPGAs. Input leakage is ±1µA max, so high-impedance sources may drift - but intentional use of internal logic thresholds eliminates need for external biasing in standard designs.

Can the MAX4052CEE+ operate with a +3.3V single supply?

Yes, the MAX4052CEE+ operates with a +3.3V single supply (V+ = +3.3V, V− = GND). At this voltage, typical on-resistance rises to ~525Ω (max 700Ω), and turn-on time increases to ~600ns, but all logic thresholds and leakage specs remain valid. The device is fully specified down to +2.7V, making it suitable for modern low-voltage embedded systems where +3.3V is standard.

How does the MAX4052CEE+ handle signal directionality - is it truly bidirectional?

Yes, the MAX4052CEE+ is fully bidirectional: NO and COM pins are electrically identical and interchangeable. Signals pass with equal performance in either direction - from NO to COM or COM to NO - with identical on-resistance, capacitance, and leakage characteristics. This allows flexible use as input selectors, output routers, or signal isolators without design constraints on signal flow direction.

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

INH (Inhibit) is an active-high digital input that forces all analog switches open (high-impedance state) regardless of address inputs. It should be tied to GND for normal operation. Driving INH high disables both 4:1 sections simultaneously - useful for power-saving modes, fault isolation, or preventing signal contention during system reset. The MAX4052CEE+ guarantees break-before-make timing even during INH assertion.
