Product details
Overview
MAX4712ESE+ from Maxim Integrated is a fault-protected, quad SPST analog switch with four normally open (NO) channels, rail-to-rail signal handling, 25Ω max on-resistance at +25°C, ±12V fault protection with power off, and operation from single +2.7V to +11V or dual ±2.7V to ±5.5V supplies. It serves as a robust signal routing element in battery-powered test equipment requiring overvoltage resilience.
For engineers reviewing the MAX4712ESE+ datasheet, MAX4712ESE+ pinout, MAX4712ESE+ application, or MAX4712ESE+ equivalent, this page delivers verified specifications, fault-protection behavior under ±5V and +5V supply conditions, real-world leakage and timing data, and pin-compatible alternatives for industrial signal-switching designs.
Technical Context
The MAX4712ESE+ employs parallel N- and P-channel FETs per channel to achieve low RON and flat on-resistance across the signal range. Its dual comparator-based fault-sensing circuit detects NO-pin excursions beyond V+ or V− by ~150mV, disabling the main switch and activating clamp FETs to limit COM output to the appropriate supply rail.
Fault response is asymmetric: positive faults engage P2 clamping to V+, negative faults engage N2 clamping to V−, each sourcing/sinking up to ±15mA. During power-off, NO pins remain high-impedance with ±12V fault tolerance, while COM pins retain no fault protection and rely on internal ESD diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 25Ω max at +25°C, +4.5V/−4.5V supplies - ensures minimal signal attenuation in precision analog paths |
| On-resistance match | 1Ω max between channels - critical for matched gain/phase in multi-channel instrumentation |
| Fault protection (power off) | ±12V on NO/NC pins - enables safe hot-plug or sensor disconnect without external protection |
| Turn-on/off time | <125ns tON, <80ns tOFF - supports high-speed multiplexing in automated test systems |
| Supply range | +2.7V to +11V (single) or ±2.7V to ±5.5V (dual) - compatible with Li-ion, 3.3V, 5V, and ±5V legacy systems |
| Logic compatibility | TTL/CMOS thresholds (VIH = 2.4V, VIL = 0.8V at ±5V or +5V) - eliminates level-shifter requirements |
| Off-isolation | −59dB at 1MHz - suppresses crosstalk in dense signal-routing PCB layouts |
Pinout & Package
MAX4712ESE+ is housed in a 16-pin narrow SO package (SOIC-16, 150 mil width), RoHS-compliant, with standard JEDEC MO-153 footprint and 1.27mm pitch.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Fault-protected logic inputs; accept +0.8V to +2.4V thresholds; tolerate up to (V− + 12V) |
| 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; clamp to V+ or V− during overvoltage; ±12V tolerant with power off |
| 4 | V− | Negative supply input; connect to GND for single-supply operation |
| 5 | GND | Ground reference for logic and substrate; decoupling required near pin |
| 12 | N.C. | No internal connection - leave unconnected |
| 13 | V+ | Positive supply input; supports up to +11V; powers internal bias and clamp circuits |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Signals from V− to V+ pass unattenuated in both directions - preserves full dynamic range of sensors or DAC outputs |
| Fault-clamped COM output | During NO-pin overvoltage, COM is actively clamped to V+ or V− - prevents downstream IC damage without external TVS |
| Power-off fault protection | NO/NC pins remain high-Z with ±12V tolerance even with V+/V− = 0 - essential for maintenance-safe system architecture |
| Pin-compatible upgrade | Direct replacement for MAX392 with identical SOIC-16 pinout - enables drop-in reliability enhancement in existing designs |
| Low charge injection | 25pC typical - minimizes voltage glitch on high-impedance nodes (e.g., sample-and-hold, ADC front-ends) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX392ESE+ | No fault protection; 35Ω max RON; same SOIC-16 pinout; lower cost | Suitable only where external overvoltage protection is already implemented | Select when system-level fault protection exists and BOM cost is prioritized over integration |
| ADG1412BRUZ | 4-channel, SPST, NO; ±15V supply; 1.8Ω max RON; no power-off fault tolerance | Higher performance for precision DC-coupled applications but requires external ±12V fault clamps | Choose for ultra-low RON and wide supply range where fault events are rare and externally managed |
Compared with MAX392ESE+, MAX4712ESE+ adds integrated ±12V fault protection with zero layout change; compared with ADG1412BRUZ, it trades lower RON for guaranteed power-off safety and simpler system-level design.

FAQ
What is the maximum fault voltage the MAX4712ESE+ can withstand with power removed?
The MAX4712ESE+ guarantees ±12V fault tolerance on its NO_ pins even when V+ and V− are disconnected or at 0V. This allows safe handling of unplanned voltage transients during maintenance or hot-swap operations without risk of latch-up or permanent damage. The specification is production-tested and applies regardless of ambient temperature.
Does the MAX4712ESE+ support single-supply operation below 3V?
Yes, the MAX4712ESE+ operates from +2.7V to +11V in single-supply mode (V− tied to GND). At +2.7V, it maintains rail-to-rail switching with 100Ω max RON, VIH = 2.0V, and VIL = 0.6V - enabling direct interface with low-voltage microcontrollers and energy-harvesting systems.
How does the fault-clamp behavior differ between positive and negative overvoltage events on the MAX4712ESE+?
During positive faults (> V+ + ~150mV), the MAX4712ESE+ activates P2 to clamp COM_ to V+; during negative faults (< V− − ~150mV), it activates N2 to clamp COM_ to V−. Both clamp paths can source/sink up to ±15mA, but recovery time differs: +fault recovery is ~500ns, −fault recovery is ~700ns under typical load conditions.
Can the COM pins of the MAX4712ESE+ be driven beyond the supply rails?
No - COM pins lack fault protection. Exceeding V+ or falling below V− forward-biases internal ESD diodes, risking excessive current flow and potential device failure. Absolute maximum ratings specify COM_ voltage range as (V− − 0.3V) to (V+ + 0.3V); external clamping is mandatory if overvoltage is possible at COM.
Is the MAX4712ESE+ pin-compatible with non-fault-protected switches in the same package?
Yes - the MAX4712ESE+ uses the industry-standard SOIC-16 pinout shared with MAX392, DG412, and ADG1412. However, only NO_/NC_ pins are fault-protected; COM_ pins retain identical behavior. Layout reuse is valid, but system-level fault analysis must confirm COM-side protection remains adequate.
