Analog Devices Inc./Maxim Integrated MAX4053EEE+

Overview

MAX4053EEE+ from Maxim Integrated is a triple single-pole/double-throw (SPDT) CMOS analog switch designed for low-voltage signal routing in precision instrumentation and battery-powered systems. It operates from ±2.7V to ±8V dual supplies or +2.7V to +16V single supply, delivers 100Ω typical on-resistance at ±5V, guarantees 6Ω channel-to-channel on-resistance match (A-suffix), and supports rail-to-rail analog signals up to ±5V with <0.04% THD at 600Ω load.

For engineers reviewing the MAX4053EEE+ datasheet, MAX4053EEE+ pinout, MAX4053EEE+ application, or MAX4053EEE+ equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), sub-0.1nA off-leakage at +25°C, break-before-make timing (≤75ns), high off-isolation (<–90dB at 100kHz), and compatibility with TTL/CMOS logic levels across supply ranges.

Technical Context

The MAX4053EEE+ implements three independent SPDT switches using matched CMOS transmission gates driven by address-decoded logic. Each switch features symmetrical bidirectional conduction, no ground reference for analog paths, and ESD-protection diodes clamping NO/COM pins to V+ and V−.

Its digital interface uses ADDA/ADDB inputs to select one of four NO/NC pairs per switch, with INH enabling global disable. Logic thresholds (0.8V to 2.4V) ensure compatibility with +5V TTL/CMOS, while internal level translators isolate digital control from analog supply domains.

Key Specifications

Pinout & Package

FAQ

What is the maximum analog signal voltage range supported by the MAX4053EEE+?

The MAX4053EEE+ supports rail-to-rail analog signals from V− to V+, limited only by its absolute maximum ratings. With ±5V supplies, the usable range is –4.7V to +4.7V; with +5V single supply (V− = GND), it spans 0V to +4.7V. Exceeding V+ or V− forward-biases internal ESD diodes, so signal clamping must be externally managed if overvoltage risk exists.

Does the MAX4053EEE+ require external pull-up or pull-down resistors on its ADDA/ADDB inputs?

No, the MAX4053EEE+ does not require external biasing on ADDA or ADDB. Its TTL/CMOS-compatible inputs have defined logic thresholds (0.8V low, 2.4V high) and low input current (±1µA), allowing direct connection to microcontroller GPIOs or FPGA outputs without pull resistors-reducing component count and layout complexity.

How does the MAX4053EEE+ achieve 6Ω on-resistance matching between channels?

The MAX4053EEE+ achieves 6Ω max ΔRON through laser-trimmed, process-matched CMOS transistor pairs within each SPDT switch. This matching is fully characterized and guaranteed for the A-suffix variant (MAX4053A), ensuring consistent gain and offset across channels in differential or multiplexed sensor interfaces where ratio-metric accuracy is critical.

Can the MAX4053EEE+ operate reliably from a +3.3V single supply?

Yes, the MAX4053EEE+ operates from +2.7V to +16V single supply. At +3.3V, typical on-resistance rises to ~250Ω (vs. 100Ω at ±5V), and switching times increase moderately-but leakage remains below 0.1nA at +25°C. This makes it viable for low-power 3.3V systems where signal integrity and leakage dominate over on-resistance.

What is the purpose of the INH pin on the MAX4053EEE+?

INH is the global inhibit input: driving it high disables all three SPDT switches simultaneously, forcing open-circuit isolation regardless of ADDA/ADDB state. This enables system-level power gating, sleep-mode isolation, or fault-safe shutdown-replacing multiple enable lines with a single control signal and simplifying firmware logic for the MAX4053EEE+.
