Analog Devices Inc./Maxim Integrated MAX4053ACEE+T

Overview

MAX4053ACEE+T from Maxim Integrated is a triple single-pole/double-throw (SPDT) CMOS analog switch optimized for low-voltage, rail-to-rail signal routing. It features guaranteed 100Ω on-resistance at ±5V supplies, 6Ω channel-to-channel on-resistance match (A-suffix), and 0.1nA off-leakage at +25°C. Designed for battery-powered audio/video switching and low-voltage data acquisition systems, it operates from single +2.7V to +16V or dual ±2.7V to ±8V supplies.

For engineers reviewing the MAX4053ACEE+T datasheet, MAX4053ACEE+T pinout, MAX4053ACEE+T application, or MAX4053ACEE+T equivalent, key selection criteria include on-resistance flatness over signal range, break-before-make timing, charge injection (<10pC), off-isolation (<–90dB at 100kHz), and TTL/CMOS logic compatibility with ±5V or +5V supply.

Technical Context

The MAX4053ACEE+T implements three independent SPDT switches using matched CMOS transmission gates driven by address-decoded logic. Each switch supports bidirectional rail-to-rail analog signals with no ground reference required-signal paths are bounded only by V+ and V– rails.

Its A-suffix grade guarantees tight parametric matching: ≤6Ω on-resistance variation between channels and ≤10Ω on-resistance flatness across the full analog input range. Internal ESD protection diodes clamp NO/COM pins to V+ and V–, enabling robust operation but requiring proper supply sequencing to avoid forward conduction.

Key Specifications

FAQ

What is the maximum analog signal voltage range supported by the MAX4053ACEE+T?

The MAX4053ACEE+T supports rail-to-rail analog signals from V– to V+. With ±5V dual supplies, this means –5V to +5V; with +5V single supply (V– = GND), it supports 0V to +5V. Absolute maximum ratings allow V+ up to +17V and V– down to –17V, but operational analog range remains bounded by the applied supply rails. The MAX4053ACEE+T does not require a ground reference for analog signals.

Does the MAX4053ACEE+T require external pull-up or pull-down resistors on its digital control lines?

No, the MAX4053ACEE+T does not require external pull-up or pull-down resistors on ADDA, ADDB, ADDC, or INH pins. Its TTL/CMOS-compatible logic thresholds (0.8V low, 2.4V high at +5V supply) ensure reliable operation with direct connection to microcontroller GPIOs. Input leakage is ±1µA max, so standard MCU outputs drive these inputs cleanly without added components.

How does the MAX4053ACEE+T handle power-supply sequencing, and what happens if V– is powered before V+?

Proper sequencing-V+ first, then V–, then logic and analog signals-is recommended for the MAX4053ACEE+T. If V– powers before V+, internal ESD diodes from NO/COM pins to V– may become forward-biased if analog signals are present, causing unintended current flow and potential damage. The MAX4053ACEE+T datasheet specifies absolute maximum ratings to prevent this; violating sequencing risks latch-up or accelerated wear.

Can the MAX4053ACEE+T be used in a single-supply +3.3V system, and what performance trade-offs occur?

Yes, the MAX4053ACEE+T operates down to +2.7V single supply. At +3.3V, typical on-resistance rises to ~525Ω (vs. 100Ω at ±5V), and turn-on time increases to ~600ns. Off-leakage remains 0.1nA at +25°C, preserving accuracy, but designers must verify signal integrity in high-Z paths due to higher RON and reduced drive strength. The MAX4053ACEE+T maintains full logic compatibility at +3.3V.

What is the purpose of the INH (inhibit) pin on the MAX4053ACEE+T, and how should it be used in system design?

INH is a global enable/disable control for all three SPDT switches in the MAX4053ACEE+T. When pulled high (≥2.4V), all switches open regardless of address inputs-providing fail-safe isolation. In normal operation, INH is tied to GND or driven low. It allows centralized shutdown (e.g., during power-down or fault conditions) without reconfiguring address lines, simplifying safety-critical system design. The MAX4053ACEE+T draws minimal current when INH is asserted.
