Product details
Overview
The MAX4518EEE+T from Maxim Integrated is a precision 4-channel CMOS analog multiplexer with <100Ω on-resistance, <4Ω channel-to-channel matching, <5pC charge injection, rail-to-rail signal handling, and operation from +2.7V to +15V single supply or ±2.7V to ±8V dual supplies. It serves as a low-leakage, low-distortion signal routing switch in battery-powered data-acquisition and test equipment.
For engineers reviewing the MAX4518EEE+T datasheet, MAX4518EEE+T pinout, MAX4518EEE+T application, or MAX4518EEE+T equivalent, this page delivers verified specifications, QSOP-16 package details, leakage and switching performance at -40°C to +85°C, and real-world selection guidance for precision analog switching.
Technical Context
The MAX4518EEE+T implements a monolithic CMOS analog switch architecture with guaranteed flat on-resistance (<10Ω variation over full signal range) and break-before-make timing (200ns typical). Its logic-compatible enable and address inputs (A0/A1) control one of four normally-open analog paths between COM and NO1–NO4.
Designed using Maxim's low-voltage silicon-gate process, it achieves <2nA NO-off leakage at +85°C and >2000V ESD protection. The device supports unbalanced supplies (e.g., +10V/−5V), maintains TTL/CMOS input compatibility, and delivers <250ns transition time under ±5V dual-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | <100Ω max - ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Matching | <4Ω between channels - enables accurate ratiometric measurements and multi-channel calibration |
| Charge Injection | <5pC - reduces voltage glitch and settling error in sample-and-hold and ADC front-end circuits |
| NO-Off Leakage | <2nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-monitoring nodes |
| Supply Range | +2.7V to +15V (single) or ±2.7V to ±8V (dual) - supports wide-input industrial and portable systems without level-shifting |
| Transition Time | <250ns - enables fast channel switching in automated test equipment and real-time signal routing |
| Operating Temperature | −40°C to +85°C - qualified for industrial and extended-temperature embedded applications |
Pinout & Package
MAX4518EEE+T is housed in a 16-pin QSOP package (3.9mm × 4.9mm, 0.635mm pitch), optimized for high-density PCB layouts and thermal performance in industrial environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 16 | A1, A0 | Binary address inputs selecting one of four analog channels (NO1–NO4) when EN = high |
| 2 | GND | Logic ground reference; connects to system ground plane for noise immunity and stable logic thresholds |
| 3, 15 | V+, V− | Positive/negative supply rails; V− tied to GND enables single-supply operation with rail-to-rail analog swing |
| 4, 11, 12, 13 | NO1–NO4 | Normally-open analog inputs; each forms a low-leakage, low-RON path to COM when selected |
| 6 | COM | Common analog terminal - bidirectional signal path shared across all four switched channels |
| 7 | EN | Active-high enable input; disables all switches (high-Z state) when low, reducing system power and crosstalk |
| 8, 9, 10, 14 | N.C. | Not internally connected - must remain unconnected per datasheet; no pull-up/down or routing required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale sensor output capture |
| Guaranteed flat on-resistance | <10Ω variation over entire signal range - eliminates gain nonlinearity in precision instrumentation amplifiers |
| TTL/CMOS logic compatibility | Input thresholds (0.8V/2.4V) compatible with 3.3V/5V microcontrollers - eliminates external level shifters |
| Low power consumption | <300µW typical - extends battery life in portable medical and field-test devices |
| ESD protection | >2000V HBM - enhances robustness during board assembly and end-user handling in industrial settings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1418BRUZ | 8-channel, ±15V supply, 1.3Ω RON, but higher 12nA leakage at +85°C and no guaranteed RON matching | Better for high-channel-count industrial PLC I/O; less suitable for ratiometric sensor arrays requiring tight matching | Select ADG1418BRUZ only if channel count >4 is required and leakage tolerance >5nA is acceptable. |
| TS5A23157DGSR | 2-channel, +1.65V to +5.5V supply, 0.9Ω RON, but only rated to +85°C with no specified RON flatness or charge injection | Optimized for low-voltage portable audio routing; lacks dual-supply support and precision specs for measurement-grade use | Choose TS5A23157DGSR for cost-sensitive consumer audio; avoid where rail-to-rail swing or sub-5pC charge injection is mandatory. |
Compared with ADG1418BRUZ and TS5A23157DGSR, the MAX4518EEE+T uniquely combines 4-channel integration, guaranteed <4Ω RON matching, <5pC charge injection, and dual-supply flexibility-making it the only option qualified for precision, temperature-stable analog multiplexing in industrial and test systems.

FAQ
What is the maximum analog signal range supported by the MAX4518EEE+T?
The MAX4518EEE+T supports analog signals from V− to V+ across its full operating supply range. With ±5V dual supplies, the range is ±4.5V; with +5V single supply (V− = GND), it is 0V to 4.5V. This rail-to-rail capability ensures full utilization of ADC input ranges and preserves dynamic range in precision signal chains - a key design feature confirmed in the MAX4518EEE+T datasheet's Electrical Characteristics tables.
Does the MAX4518EEE+T require external pull-up resistors on its address or enable pins?
No, the MAX4518EEE+T does not require external pull-up resistors. Its CMOS logic inputs (A0, A1, EN) have high impedance and standard TTL/CMOS thresholds (0.8V low, 2.4V high), allowing direct interfacing with microcontroller GPIOs. Input leakage is specified at ±0.1µA - low enough to prevent unintended switching without external biasing, as verified in the MAX4518EEE+T's Digital Logic Input section.
Can the MAX4518EEE+T operate with unbalanced supplies like +10V and −5V?
Yes, the MAX4518EEE+T supports unbalanced supplies such as +10V and −5V, provided the absolute difference between V+ and V− does not exceed 17V and neither rail violates its individual absolute maximum rating (−0.3V to +17V for V+, +0.3V to −17V for V−). This flexibility is explicitly documented in the MAX4518EEE+T Applications Information section and validated in Typical Operating Characteristics graphs.
What is the guaranteed on-resistance flatness specification for the MAX4518EEE+T?
The MAX4518EEE+T guarantees on-resistance flatness of ≤10Ω over its specified analog signal range (e.g., ±4.5V with ±5V supplies). This parameter - defined as the difference between maximum and minimum RON measured across the full signal swing - ensures consistent gain and linearity in precision amplifier and filter applications, as confirmed in the MAX4518EEE+T's Dual-Supply Electrical Characteristics table.
Is the MAX4518EEE+T pin-compatible with other variants in the MAX4518 family?
Yes, the MAX4518EEE+T shares identical pinout and footprint with all MAX4518 variants in QSOP-16 packaging (e.g., MAX4518CSE+T, MAX4518ESE+T), differing only in temperature grade and screening. The pin configuration is fixed per the MAX4518 top-view diagram, and N.C. pins (8, 9, 10, 14) remain unconnected across all versions - ensuring drop-in replacement within the same package type, as documented in the MAX4518EEE+T Ordering Information table.
