Product details
Overview
MAX4518CEE from Maxim Integrated is a precision 4-channel CMOS analog multiplexer with ≤100Ω on-resistance, <4Ω channel-to-channel matching, and <5pC charge injection. It operates from single +2.7V to +15V or bipolar ±2.7V to ±8V supplies and delivers rail-to-rail signal handling for low-voltage data-acquisition systems and battery-operated instrumentation.
For engineers reviewing the MAX4518CEE datasheet, MAX4518CEE pinout, MAX4518CEE application, or MAX4518CEE equivalent, this page provides verified specifications, QSOP-16 package details, leakage performance at +85°C, switching timing under dual/single supply conditions, and real-world routing use cases in military radios and heads-up displays.
Technical Context
The MAX4518CEE implements a monolithic CMOS switch architecture with silicon-gate process optimization for minimal charge injection and ESD robustness (>2000V). Its enable-controlled 4:1 analog mux uses two address bits (A0/A1) to select one of four NO inputs to the common COM terminal.
All channels exhibit flat on-resistance (<10Ω variation over full analog signal range) and guaranteed leakage: NO-off <2nA and COM-off <5nA at +85°C. Logic inputs are TTL/CMOS-compatible with rail-to-rail operation and <300µW total power consumption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | ≤100Ω max - ensures minimal signal attenuation and gain error in precision signal routing |
| On-Resistance Matching | <4Ω between channels - critical for multi-channel instrumentation requiring matched gain paths |
| Charge Injection | <5pC - limits voltage glitch and settling error in sample-and-hold circuits |
| NO-Off Leakage | <2nA at +85°C - preserves accuracy in high-impedance sensor front-ends |
| Supply Range | +2.7V to +15V (single) or ±2.7V to ±8V (dual) - supports portable and industrial supply rails |
| Transition Time | <250ns - enables fast channel switching in automatic test equipment |
| ESD Protection | >2000V HBM - enhances reliability during board handling and system integration |
Pinout & Package
MAX4518CEE is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.65mm lead pitch and exposed pad not connected internally. Pin functions are validated per Maxim's official pin configuration diagram and functional truth table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A1 / A0 | Binary address inputs selecting active channel (00→NO1, 01→NO2, 10→NO3, 11→NO4) |
| 2 | GND | Logic ground reference for digital control signals |
| 3 | V+ | Positive supply rail - connects to +2.7V–+15V (single) or +2.7V–+8V (dual) |
| 4, 5, 12, 13 | NO1–NO4 | Analog normally-open inputs - only one conducts to COM when selected |
| 6 | V- | Negative supply rail - ties to GND for single supply, or -2.7V to -8V for dual supply |
| 7 | EN | Active-high enable - disables all switches when low, reducing leakage and power |
| 8 | COM | Common analog output terminal - routed to selected NO input when enabled |
| 9–11, 14, 15 | N.C. | Not internally connected - no electrical function; must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for ±5V or +3.3V systems |
| Guaranteed flat on-resistance | <10Ω variation across full signal range - maintains linearity in precision measurement paths |
| Low power consumption | <300µW typical - extends battery life in portable medical and test equipment |
| TTL/CMOS logic compatibility | Input thresholds (0.8V/2.4V) interface directly with microcontrollers and FPGAs without level shifters |
| Break-before-make switching | Guaranteed tOPEN ≥200ns - prevents momentary shorting between channels during address changes |
Applications
| Sample-and-Hold Circuits | Automatic Test Equipment |
|---|---|
Use Scenario: Multiplexing multiple sensor outputs into a single ADC input while maintaining acquisition fidelity. IC Role / Device Role / Timing Role: 4:1 analog switch providing low-charge-injection path selection before hold capacitor.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | 4-channel, ±15V supply capable, RON = 1.3Ω (typ), higher cost, SOIC-16 | Better performance in high-voltage industrial DAQ; not qualified for extended temp | Select when ultra-low RON and wider supply range outweigh cost and temp grade needs |
| TS5A23157DGSR | Dual SPDT, 5V-only supply, RON = 0.9Ω (typ), lower leakage (100pA), smaller US8 package | Optimized for low-voltage consumer portables; lacks enable pin and wide supply flexibility | Choose for space-constrained 3.3V designs where enable control and bipolar operation are unnecessary |
Compared with MAX4518CEE, ADG1419BRUZ offers superior on-resistance and voltage range but lacks extended temperature support and costs significantly more; TS5A23157DGSR provides better leakage and size efficiency at the expense of supply flexibility and enable functionality required in programmable test systems.

FAQ
What is the maximum analog signal range supported by the MAX4518CEE?
The MAX4518CEE supports rail-to-rail analog signals from V− to V+. With ±5V dual supplies, that is ±4.5V; with +5V single supply (V− = GND), it is 0V to +4.5V. The device guarantees flat on-resistance and low leakage across these ranges, making MAX4518CEE suitable for precision signal routing without external level-shifting circuitry.
Does the MAX4518CEE require external pull-up resistors on its address or enable pins?
No, the MAX4518CEE features CMOS logic inputs with standard TTL/CMOS-compatible thresholds (VIL ≤ 0.8V, VIH ≥ 2.4V) and input leakage <±0.1µA. Direct connection to microcontroller GPIOs or FPGA outputs is sufficient; MAX4518CEE does not require external pull-ups unless system-level noise immunity dictates otherwise.
Can the MAX4518CEE operate reliably at −40°C?
Yes - the MAX4518CEE variant is rated for −40°C to +85°C operation (industrial temperature grade). Electrical characteristics including on-resistance matching (<4Ω), charge injection (<5pC), and leakage (<2nA NO-off at +85°C) are fully specified and tested across this range, confirming MAX4518CEE suitability for harsh-environment deployments.
How does the enable (EN) pin affect leakage current in the MAX4518CEE?
When EN is low, all internal switches open and digital inputs are disabled, reducing total supply current to <1µA and suppressing NO-off and COM-off leakage to sub-picoampere levels. This state minimizes power and signal coupling in standby mode - a key advantage of MAX4518CEE in battery-powered systems requiring intermittent sampling.
Is the MAX4518CEE pin-compatible with other devices in the MAX4518/MAX4519 family?
Yes - MAX4518CEE shares identical pinout and function mapping with MAX4518CPD (DIP-14) and MAX4518CSD (SO-14) in the same temperature grade, except for N.C. pin count differences due to package geometry. All MAX4518 variants use the same A0/A1/EN/COM/NOx signal assignments, allowing MAX4518CEE to drop into QSOP-16 layouts designed for functional compatibility.
