Product details

Overview

MAX4712EUE+T from Maxim Integrated is a fault-protected, quad SPST analog switch with normally open (NO) configuration, designed for signal routing in ±2.7V to ±5.5V dual-supply or +2.7V to +11V single-supply systems. It delivers 25Ω max on-resistance at +25°C, <125ns turn-on time, and ±12V fault protection on NO/NC pins with power off - enabling robust operation in battery-powered test equipment and industrial I/O modules.

For engineers reviewing the MAX4712EUE+T datasheet, MAX4712EUE+T pinout, MAX4712EUE+T application, or MAX4712EUE+T equivalent, key selection criteria include fault-protection voltage margins under varying supply conditions (+3V/+5V/±5V), on-resistance flatness across rail-to-rail signal range, leakage performance at temperature extremes, and pin compatibility with MAX392.

Technical Context

The MAX4712EUE+T integrates parallel N- and P-channel FETs per channel to achieve low R_ON and rail-to-rail signal handling. Its dual comparator-based fault-sensing circuit detects input overvoltage (>V+ +150mV or

Fault response is asymmetric: positive faults engage P2 clamp sourcing current from V+, negative faults engage N2 clamp sinking to V−, both capable of ±15mA. During power-off, NO/NC pins remain fault-protected up to ±12V, while COM pins rely on internal ESD diodes and require external voltage limiting.

Key Specifications

Parameter	Value and Actual Design Meaning
On-resistance (R_ON)	25Ω max at +25°C, +4.5V/−4.5V supplies - ensures minimal signal attenuation in precision analog paths
R_ON match between channels	1Ω max - enables matched gain/attenuation in multi-channel instrumentation
Turn-on time (t_ON)	<125ns at +4.5V/−4.5V - supports high-speed multiplexing in data acquisition
Fault protection (power off)	±12V on NO/NC pins - allows safe connection to unpowered subsystems during hot-swap or maintenance
Supply range	+2.7V to +11V single or ±2.7V to ±5.5V dual - supports wide battery and industrial rail flexibility
Logic compatibility	TTL/CMOS with VIH = +2.4V, VIL = +0.8V at ≥+4.5V supply - simplifies interface to microcontrollers and FPGAs
Off-isolation	−59dB at 1MHz - suppresses crosstalk between inactive channels in dense signal routing

Pinout & Package

MAX4712EUE+T is housed in a 16-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch) rated for −40°C to +85°C operation.

Pin	Circuit Role	Design Meaning
1, 8, 9, 16	IN1–IN4	Fault-protected logic inputs; accept +0.8V to +2.4V thresholds for TTL/CMOS compatibility
2, 7, 10, 15	COM1–COM4	Analog common terminals; not fault-protected - must stay within V− to V+ to avoid ESD diode conduction
3, 6, 11, 14	NO1–NO4	Fault-protected normally open analog inputs; tolerate ±12V with power off, clamp to rails during fault
4	V−	Negative supply input; connect to GND for single-supply operation
5	GND	Ground reference for logic and analog sections
12	N.C.	No internal connection - leave unconnected
13	V+	Positive supply input; supports up to +11V or ±5.5V differential

Key Features

Feature	Design Value
Fault-protected NO inputs	Withstands ±12V transients on NO pins even with power removed - eliminates need for external TVS in field-connected I/O
Rail-to-rail signal handling	Passes signals from V− to V+ without distortion - enables full dynamic range utilization in sensor front-ends
Output clamping during fault	COM output limited to V+ or V− polarity during overvoltage - protects downstream ADCs, amplifiers, or microcontroller pins
Pin-compatible with MAX392	Direct drop-in replacement for legacy non-fault-protected switches - reduces redesign effort in existing PCBs
Low charge injection (25pC)	Minimizes voltage glitch on high-impedance nodes during switching - critical for precision sample-and-hold circuits

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX392ESE+	No fault protection; 35Ω max R_ON; same 16-pin SO package and pinout	Suitable only in controlled environments with pre-conditioned signals - requires external protection circuitry for field use	Select when cost sensitivity outweighs fault tolerance and board space allows discrete TVS diodes
ADG1412BRUZ	4-channel, SPST, NO; ±15V supply rating; 1.8Ω max R_ON; no built-in fault clamping	Higher voltage rating but lacks integrated fault response - needs external comparator/clamp circuit for equivalent protection	Choose for ultra-low R_ON in high-precision instrumentation where external protection is already implemented

Compared with MAX392ESE+ and ADG1412BRUZ, the MAX4712EUE+T uniquely integrates ±12V fault protection with rail-to-rail switching and sub-125ns speed in a drop-in-compatible footprint - eliminating external protection components while maintaining timing integrity in safety-critical routing.

FAQ

What is the maximum fault voltage the MAX4712EUE+T can withstand on its NO pins with power removed?

The MAX4712EUE+T guarantees ±12V fault protection on NO pins even when powered down. This is explicitly specified in the Absolute Maximum Ratings table and confirmed in the Fault-Protected Analog Signal Range section for "Power off" condition. The device achieves this via internal high-impedance state and protection structures that remain active without bias - making it ideal for hot-plug or maintenance scenarios where external signals may be present before system power-up. MAX4712EUE+T maintains this rating across its full −40°C to +85°C operating range.

Does the MAX4712EUE+T support single-supply operation, and what is the minimum supply voltage?

Yes, the MAX4712EUE+T supports single-supply operation with V− connected to GND. Its specified minimum supply voltage is +2.7V, validated across electrical characteristics tables for +3V operation (including R_ON, leakage, and timing). At +2.7V, typical turn-on time is 500ns and on-resistance rises to 100Ω max - parameters fully characterized and guaranteed in the +3V Single Supply section. MAX4712EUE+T remains functional up to +11V, enabling direct integration into wide-input-range power architectures.

Is the MAX4712EUE+T pin-compatible with industry-standard analog switches?

Yes, the MAX4712EUE+T features identical pinout to the MAX392 series (e.g., MAX392ESE+), as stated in the Features list and Pin Compatibility section. All IN, COM, NO, V+, V−, GND, and N.C. assignments match exactly across the 16-pin TSSOP/SO packages. However, caution is advised: only NO/NC pins are fault-protected in the MAX4712EUE+T, while COM pins retain standard CMOS behavior - so existing layouts must ensure COM traces do not exceed V+ or V− rails. MAX4712EUE+T enables seamless upgrade paths where fault tolerance is added without PCB revision.

What is the on-resistance match between channels for the MAX4712EUE+T, and why does it matter?

The MAX4712EUE+T guarantees ≤1Ω maximum on-resistance match (∆R_ON) between any two channels under dual ±4.5V supply conditions at +25°C. This tight matching ensures uniform signal attenuation across all four switched paths - critical in applications like multi-channel data acquisition or programmable gain amplifiers where channel-to-channel gain error directly impacts measurement accuracy. The spec is tested and guaranteed per the Electrical Characteristics table, and remains ≤3Ω at +3V supply. MAX4712EUE+T's matched performance reduces calibration burden and improves system-level linearity.

How does the fault recovery time of the MAX4712EUE+T affect system timing in real-time applications?

The MAX4712EUE+T exhibits a typical fault recovery time of 700ns (dual supply) or 500µs (single +5V supply) after an overvoltage event subsides - meaning the switch resumes normal conduction only after this delay. This parameter is measured with 1kΩ load and impacts real-time systems requiring rapid fault-clearance response, such as automated test equipment with tight sequencing windows. Designers must budget this delay into control-loop timing; for sub-microsecond recovery, the dual-supply configuration is mandatory. MAX4712EUE+T's recovery behavior is deterministic and documented in the Fault Recovery Time specification.
