Analog Devices Inc./Maxim Integrated MAX4052ESE

Overview

MAX4052ESE from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional 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 achieves <−90dB off-isolation and crosstalk at 100kHz - enabling precision audio and data-acquisition switching.

For engineers reviewing the MAX4052ESE datasheet, MAX4052ESE pinout, MAX4052ESE application, or MAX4052ESE equivalent, key selection criteria include guaranteed on-resistance flatness (≤18Ω), sub-0.1nA off-leakage at +25°C (A-grade), break-before-make timing (≤200ns), rail-to-rail analog signal handling, and pin compatibility with 74HC4052.

Technical Context

The MAX4052ESE implements two independent 4:1 analog multiplexers using matched CMOS transmission gates, each controlled by three digital address inputs (ADDA, ADDB, INH) and sharing V+, V−, and GND rails. Its internal logic-level translators ensure TTL/CMOS compatibility across supply voltages from +2.7V to +16V or ±2.7V to ±8V.

Each multiplexer section features rail-to-rail analog signal capability, low charge injection (≤10pC), and symmetrical on-capacitance (8pF) and off-capacitance (2pF per NO/COM terminal), supporting high-fidelity signal routing up to 50MHz in 50Ω systems with minimal distortion (<0.04% THD at 600Ω).

Key Specifications

Pinout & Package

MAX4052ESE is housed in a 16-pin narrow SO (Small Outline) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.2mm × 5.3mm body size, and exposed pad not present. Pin 1 is marked by a beveled corner.

Compared with MAX4052ACSE, the MAX4052ESE trades tighter matching and lower leakage for broader temperature range (−40°C to +85°C vs. 0°C to +70°C) and cost efficiency; versus ADG408BRUZ, it provides native dual independent control but lacks integrated enable per channel.

FAQ

What supply voltage ranges does the MAX4052ESE support?

The MAX4052ESE operates from ±2.7V to ±8V dual supplies or a single +2.7V to +16V supply. At ±5V, it delivers 100Ω typical on-resistance and guarantees rail-to-rail analog signal handling. For single-supply use, tie V− to GND; the device remains functional down to +2.0V, though on-resistance rises significantly below +3V. The MAX4052ESE datasheet specifies absolute maximum ratings of V+ to V− ≤ +17V.

How does the MAX4052ESE differ from the MAX4052ACSE?

The MAX4052ESE is the standard-grade version with 12Ω max on-resistance match and 1nA max off-leakage at +25°C, rated for −40°C to +85°C operation. The MAX4052ACSE is the A-grade variant offering tighter 6Ω match and 0.1nA off-leakage, but only rated for 0°C to +70°C. Both share identical pinout, package (16-pin narrow SO), and electrical architecture - the MAX4052ESE prioritizes industrial temperature range and cost, while MAX4052ACSE targets precision matching.

Can the MAX4052ESE be used in single-supply +3.3V systems?

Yes, the MAX4052ESE supports single-supply operation from +2.7V to +16V. At +3.3V, on-resistance increases to ~250Ω (typ), and switching times lengthen, but logic thresholds (0.8V/2.4V) remain compatible with 3.3V microcontrollers. For optimal performance, use with rail-to-rail op-amps and avoid driving high-impedance loads directly. The MAX4052ESE maintains <−90dB off-isolation even at +3.3V, making it viable for low-power portable audio or sensor hubs.

What is the function of the INH pin on the MAX4052ESE?

The INH (Inhibit) pin is an active-high digital control that disables both 4:1 multiplexers simultaneously. When INH = logic high, all internal switches open regardless of ADDA/ADDB states - ensuring signal isolation during power-up, fault conditions, or system sleep modes. When INH = logic low, channel selection proceeds normally via ADDA and ADDB. This feature enables safe power sequencing and prevents unintended signal coupling in complex analog routing trees using the MAX4052ESE.

Does the MAX4052ESE require external protection diodes for overvoltage?

The MAX4052ESE integrates ESD-protection diodes between each analog pin and V+/V−, but these are not intended for continuous overvoltage clamping. If analog signals may exceed V+ or fall below V− during operation, external series diodes (e.g., 1N4148) on V+ and V− lines are recommended - though this reduces usable analog range by ~0.7V. For most applications within specified supply and signal limits, no external protection is needed. Always observe proper power sequencing: apply V+ first, then V−, then logic and analog signals.
