Analog Devices Inc./Maxim Integrated MAX4052ACPE

Overview

MAX4052ACPE 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 ≤6Ω channel-to-channel on-resistance match (A-grade), and exhibits 0.1nA max off-leakage at +25°C - enabling precision signal selection in battery-powered data acquisition.

For engineers reviewing the MAX4052ACPE datasheet, MAX4052ACPE pinout, MAX4052ACPE application, or MAX4052ACPE equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), break-before-make timing (≤75ns), TTL/CMOS logic compatibility, and verified performance across -40°C to +85°C industrial temperature range.

Technical Context

The MAX4052ACPE implements two independent 4:1 analog multiplexers using matched CMOS transmission gates, each controlled by three address bits (ADDA, ADDB, INH) with active-low inhibit. Its architecture ensures symmetrical conduction in both directions and eliminates ground reference dependency for analog signals.

It features internal logic-level translators that convert TTL/CMOS inputs into full-rail gate drive voltages for the analog switches, enabling robust operation across wide supply ranges while maintaining low charge injection (≤10pC) and high off-isolation (<-90dB at 100kHz).

FAQ

What is the maximum analog signal voltage range supported by the MAX4052ACPE?

The MAX4052ACPE supports rail-to-rail analog signals between V− and V+. With ±5V 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 analog signal swing remains bounded by the actual supply rails applied. Exceeding V+ or V− risks forward-biasing internal ESD diodes.

Does the MAX4052ACPE require external pull-up or pull-down resistors on its address pins?

No, the MAX4052ACPE does not require external pull-up or pull-down resistors on ADDA, ADDB, or INH pins. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (VIL = 0.8V, VIH = 2.4V at +5V) and draw only ±1µA input current. Direct connection to microcontroller GPIO or logic buffers is sufficient - adding resistors may degrade noise immunity or switching speed.

Can the MAX4052ACPE be used with a +3.3V single supply?

Yes, the MAX4052ACPE operates with a +3.3V single supply (V− = GND). At +3.3V, typical on-resistance increases to ~280Ω (vs. 100Ω at ±5V), and switching times lengthen (t_ON ≈ 200ns), but all specifications remain valid across the full 0°C to +85°C range. The device maintains rail-to-rail signal handling from 0V to +3.3V and retains 0.1nA off-leakage at +25°C.

How does the MAX4052ACPE handle signal directionality between NO and COM pins?

The MAX4052ACPE is fully bidirectional: NO and COM pins are functionally identical and interchangeable. Signals pass with equal performance in either direction - from NO to COM or COM to NO - because the internal CMOS transmission gates have symmetric structure and no intrinsic polarity. This allows flexible PCB layout where either side can serve as input or output without redesign.

What is the purpose of the INH pin on the MAX4052ACPE, and how should it be used?

The INH (Inhibit) pin is an active-high digital control that disables all analog switches when driven high. When INH = V+, all channels disconnect regardless of address inputs; when INH = GND or low, normal multiplexing proceeds. It provides hardware-level channel blanking for system safety, power sequencing, or synchronous shutdown - eliminating need for software-controlled address manipulation during critical transitions.
