Product details
Overview
MAX4518EEE+ from Maxim Integrated is a precision 4-channel CMOS analog multiplexer with low on-resistance (<100Ω), matched within 4Ω between channels, flat on-resistance (≤10Ω over signal range), <5pC charge injection, and rail-to-rail signal handling. It operates from single +2.7V to +15V or bipolar ±2.7V to ±8V supplies and is used in low-voltage data-acquisition systems requiring high channel-to-channel consistency.
For engineers reviewing the MAX4518EEE+ datasheet, MAX4518EEE+ pinout, MAX4518EEE+ application, or MAX4518EEE+ equivalent, this page delivers verified electrical specs, QSOP-16 terminal mapping, leakage and switching performance at -40°C to +85°C, and real-world alternatives for precision analog routing in battery-operated and military-grade systems.
Technical Context
The MAX4518EEE+ implements a monolithic CMOS switch architecture with substrate tied to V+, enabling robust ESD protection (>2000V) and low charge injection. Its enable-controlled 4:1 multiplexing uses dual address lines (A0/A1) and features break-before-make timing (200ns typical) to prevent signal shorting during channel transitions.
Designed for precision analog signal routing, it maintains guaranteed on-resistance flatness (≤10Ω) across ±4.5V analog ranges under dual-supply operation and supports TTL/CMOS logic inputs with rail-to-rail compatibility. Leakage is specified at +85°C: NO-off <2nA, COM-off <5nA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | <100Ω max at +25°C; ensures minimal signal attenuation and gain error in precision measurement paths |
| On-resistance matching | <4Ω between channels; enables accurate differential or ratiometric measurements without calibration |
| Charge injection | <5pC; limits voltage glitch on sample-and-hold capacitors, preserving ADC accuracy |
| NO-off leakage | <2nA at +85°C; prevents DC error accumulation in high-impedance sensor front-ends |
| Supply range | +2.7V to +15V single or ±2.7V to ±8V dual; supports wide industrial and battery-powered operating envelopes |
| Transition time | <250ns; allows fast channel switching in automated test equipment and real-time control loops |
| ESD protection | >2000V HBM; eliminates need for external protection in ruggedized embedded systems |
Pinout & Package
MAX4518EEE+ is housed in a 16-pin QSOP package (3.9mm × 4.9mm, 0.635mm pitch), rated for -40°C to +85°C operation. Pin functions are validated per Maxim's official pin configuration diagram for the MAX4518 family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13, 14, 15 | NO1–NO4 | Normally open analog inputs; selected one connects to COM when enabled and addressed |
| 6 | COM | Common analog output node; carries routed signal to downstream circuitry (e.g., ADC input) |
| 2 | A0 | LSB address input; selects channel pair (NO1/NO2 or NO3/NO4) with A1 |
| 16 | A1 | MSB address input; completes 2-bit decoding for 4-channel selection |
| 8 | EN | Active-high enable; disables all switches (high-Z) when low, reducing system power and crosstalk |
| 3 | V− | Negative supply rail; tied to GND for single-supply use; sets lower analog signal limit |
| 12 | V+ | Positive supply rail; defines upper analog signal limit and powers internal logic |
| 9 | GND | Logic ground reference; separate from analog ground in mixed-signal layouts to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping-critical for full-scale sensor interfaces |
| Guaranteed on-resistance flatness | ≤10Ω variation over full ±4.5V range-ensures consistent gain and linearity across input span |
| TTL/CMOS logic compatibility | Accepts 0.8V/2.4V thresholds with <0.1µA input current-reduces loading on microcontroller GPIOs |
| Low power consumption | <300µW typical-enables always-on monitoring in energy-constrained portable instruments |
| Break-before-make switching | 200ns minimum interval-prevents momentary shorts between channels during reconfiguration |

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 max supply, 1.3Ω on-resistance (lower), but 12ns transition time (faster) and 16-TSSOP package | Better suited for high-speed, high-voltage industrial PLC I/O modules where speed and voltage headroom outweigh leakage concerns | Select ADG1419BRUZ when on-resistance matching <0.5Ω and sub-15ns switching are required; MAX4518EEE+ remains preferred for ultra-low charge injection (<5pC vs. 12pC) in precision sampling. |
| TS5A23157DGSR | Dual SPDT, 5V-only supply, 0.9Ω on-resistance, 10ns transition time, but only 100nA NO-off leakage at +85°C (higher than MAX4518EEE+'s 2nA) | Ideal for cost-sensitive consumer audio routing where speed matters more than leakage or temperature range | Choose TS5A23157DGSR for compact 10-pin VSSOP designs needing fast switching at 5V; MAX4518EEE+ is superior for extended temperature (-40°C to +85°C) and low-leakage requirements in medical or aerospace systems. |
Compared with ADG1419BRUZ and TS5A23157DGSR, the MAX4518EEE+ uniquely balances ultra-low leakage (<2nA), sub-5pC charge injection, and wide supply flexibility (+2.7V to +15V or ±2.7V to ±8V), making it optimal for precision, low-power, and extended-temperature analog routing where signal fidelity is non-negotiable.

FAQ
What is the maximum analog signal range supported by the MAX4518EEE+?
The MAX4518EEE+ supports rail-to-rail analog signals from V− to V+ across its full operating supply range. With bipolar ±5V supplies, the analog range is ±4.5V; with single +5V supply, it is 0V to 4.5V. This range is guaranteed by specification-not derived-and applies directly to the MAX4518EEE+ in its 16-pin QSOP package at -40°C to +85°C.
Does the MAX4518EEE+ require external pull-up or pull-down resistors on its logic inputs?
No, the MAX4518EEE+ does not require external pull-up or pull-down resistors on A0, A1, or EN. Its CMOS inputs have guaranteed logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and draw less than 0.1µA at both logic states, allowing direct interfacing with microcontroller GPIOs. This behavior is confirmed in the Electrical Characteristics table for the MAX4518EEE+ under "Input Current with Input Voltage Low/High".
Can the MAX4518EEE+ operate with unbalanced supplies such as +10V and -5V?
Yes, the MAX4518EEE+ supports unbalanced supplies-for example, +10V and -5V-as explicitly stated in the Applications Information section. The absolute maximum rating requires |V+ − V−| ≤ 17V, and the device retains full functionality, including on-resistance flatness and leakage specifications, provided V+ and V− remain within their individual absolute maximum limits (−0.3V to +17V and +0.3V to −17V respectively).
What is the guaranteed on-resistance matching specification for the MAX4518EEE+ over temperature?
The MAX4518EEE+ guarantees on-resistance matching (∆RON = RON(max) − RON(min)) of less than 4Ω between any two channels across the full operating temperature range of −40°C to +85°C. This is a 100% tested parameter per the datasheet's Note 4 and applies specifically to the MAX4518EEE+ variant, not just the base MAX4518 family.
Is the MAX4518EEE+ pin-compatible with other variants like MAX4518CPD or MAX4518CSD?
No, the MAX4518EEE+ is not pin-compatible with MAX4518CPD (14-pin PDIP) or MAX4518CSD (14-pin SO). It uses a 16-pin QSOP footprint with dedicated pins for NO3, NO4, and N.C. positions not present in the 14-pin packages. Pin compatibility is limited to other 16-pin QSOP variants (e.g., MAX4518CEE), as confirmed by Maxim's Ordering Information table and top-view diagrams.
