Product details
Overview
MAX4518EEE from Maxim Integrated is a precision 4-channel CMOS analog multiplexer with ≤100Ω on-resistance, <4Ω channel-to-channel on-resistance matching, and rail-to-rail signal handling across ±2.7V to ±8V or +2.7V to +15V supplies. It delivers low charge injection (<5pC), <2nA NO-off leakage at +85°C, and fast transition time (<250ns), enabling high-fidelity signal routing in battery-operated data-acquisition systems.
For engineers reviewing the MAX4518EEE datasheet, MAX4518EEE pinout, MAX4518EEE application, or MAX4518EEE equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), electrostatic discharge protection (>2000V), TTL/CMOS logic compatibility, and QSOP-16 package suitability for space-constrained industrial and military-grade analog front-ends.
Technical Context
The MAX4518EEE implements a monolithic CMOS switch architecture with silicon-gate process optimization to minimize charge injection and leakage. Its enable-controlled 4:1 multiplexing uses dual address lines (A0/A1) and an active-high EN input to select one of four normally open analog paths to a common COM terminal.
It supports both single-supply (+2.7V to +15V) and bipolar-supply (±2.7V to ±8V) operation, with rail-to-rail analog signal range and guaranteed performance over –40°C to +85°C. Break-before-make timing (≤40ns) prevents signal shorting during channel switching.
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 settling error and droop in sample-and-hold circuits |
| NO-Off Leakage | <2nA at +85°C - maintains signal integrity in high-impedance sensor interfaces |
| Supply Range | +2.7V to +15V single or ±2.7V to ±8V dual - supports wide-input-range industrial and battery-powered systems |
| Transition Time | <250ns - enables fast channel switching in automated test equipment (ATE) |
| ESD Protection | >2000V HBM - enhances robustness in handling-sensitive manufacturing and field environments |
Pinout & Package
MAX4518EEE is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), optimized for thermal performance and PCB density in compact analog signal chains.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13, 14, 15 | NO1–NO4 | Normally open analog inputs - selectable as active path to COM under A0/A1/EN control |
| 6 | COM | Common analog output - single-pole, 4-throw switch node shared by all channels |
| 2 | A1 | MSB address input - selects upper/lower pair of NO inputs (NO1/NO2 vs. NO3/NO4) |
| 3 | A0 | LSB address input - selects individual channel within selected pair |
| 4 | EN | Enable logic input - high enables switching; low disables all channels (high-Z state) |
| 5, 16 | GND | Logic ground reference - decoupling required near pins for noise immunity |
| 12 | V+ | Positive supply rail - powers internal logic and switch driver circuitry |
| 7 | V− | Negative supply rail - required for bipolar operation; tied to GND for single-supply mode |
| 8–11 | N.C. | Not internally connected - must remain unconnected per datasheet |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports full analog swing from V− to V+ - eliminates level-shifting in ±5V or +3.3V systems |
| Guaranteed on-resistance flatness | <10Ω variation over full signal range - preserves linearity in precision instrumentation amplifiers |
| Low power consumption | <300µW typical - extends battery life in portable medical and test equipment |
| TTL/CMOS logic compatibility | Input thresholds at 0.8V/2.4V - interoperates directly with microcontrollers and FPGAs without level shifters |
| Break-before-make switching | <40ns interval - prevents momentary short-circuits 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, 4.7Ω on-resistance, but higher charge injection (12pC) and no guaranteed flatness spec | Better high-voltage tolerance; less suitable for sub-12-bit precision S/H due to higher charge injection | Prefer MAX4518EEE when charge injection & on-resistance flatness are critical; ADG1419BRUZ where wider supply range dominates |
| TS5A4624DCKR | Single 2-channel device, +1.65V to +3.6V only, 0.5Ω on-resistance, but limited temperature range (–40°C to +85°C not guaranteed) | Optimized for ultra-low-voltage portable audio; lacks bipolar support and high-temp leakage specs | Choose MAX4518EEE for industrial/military designs requiring dual-supply operation and guaranteed +85°C leakage; TS5A4624DCKR only for consumer-grade low-voltage apps |
Compared with ADG1419BRUZ and TS5A4624DCKR, the MAX4518EEE uniquely balances low charge injection, guaranteed on-resistance flatness, bipolar/single-supply flexibility, and extended temperature validation-making it the preferred choice for precision, ruggedized analog signal routing where measurement integrity and environmental robustness are co-prioritized.

FAQ
What is the maximum analog signal range supported by the MAX4518EEE?
The MAX4518EEE supports rail-to-rail analog signal handling from V− to V+. With bipolar supplies (±2.7V to ±8V), this yields up to ±8V range; with single supply (+2.7V to +15V), it supports 0V to V+ range. For example, at ±5V supplies, the full analog range is ±4.5V, verified per datasheet Figure 2 and Table "Analog Signal Range".
Does the MAX4518EEE require external pull-up resistors on its logic inputs?
No, the MAX4518EEE does not require external pull-ups. Its A0, A1, and EN inputs are CMOS-compatible with guaranteed logic thresholds (VAL ≤ 0.8V, VAH ≥ 2.4V) and input leakage <±0.1µA at +25°C. Internal gate structures provide sufficient noise margin, and the datasheet shows direct FPGA/microcontroller interfacing without external biasing.
Can the MAX4518EEE operate with unbalanced supplies like +10V and –5V?
Yes, the MAX4518EEE supports unbalanced supplies. The absolute maximum rating specifies V+ to V− ≤ 17V, and Applications Information explicitly states operation with asymmetric rails (e.g., +10V/–5V). Performance remains valid as long as V+ and V− individually stay within their respective limits (–0.3V to +17V for V+, +0.3V to –17V for V−).
What is the thermal performance of the MAX4518EEE in QSOP-16 package?
The MAX4518EEE in QSOP-16 has a thermal resistance θJA of 9.52°C/W (derating 9.52mW/°C above +70°C), with 762mW maximum continuous power dissipation at TA = +70°C. This allows reliable operation up to +85°C ambient when PCB copper area and airflow meet standard JEDEC guidelines for small-outline packages.
How does the MAX4518EEE ensure channel isolation during switching?
The MAX4518EEE guarantees break-before-make timing of ≤40ns (tOPEN) to prevent momentary shorts between channels. Off-isolation exceeds –75dB (typical) between COM and off-state NO pins, and crosstalk between COMA/COMB is <–92dB - measured per Figure 6 test setup with 1MHz signal and 50Ω terminations.
