Product details
Overview
MAX4518CEE+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 MAX4518CEE+T datasheet, MAX4518CEE+T pinout, MAX4518CEE+T application, or MAX4518CEE+T equivalent, this page delivers verified electrical specs, QSOP-16 package mapping, real-world use scenarios, and two validated alternative parts for design flexibility and supply continuity.
Technical Context
The MAX4518CEE+T implements a monolithic CMOS analog switch architecture with independent address decoding (A0/A1) and global enable (EN), supporting break-before-make switching with <40ns typical tOPEN. Its low-voltage silicon-gate process ensures guaranteed flat on-resistance (<10Ω variation over full analog range) and ESD robustness >2000V HBM.
It supports bidirectional signal flow, TTL/CMOS-compatible logic inputs, and operates across -40°C to +85°C (industrial grade). Leakage is tightly controlled: NO-off current <2nA and COM-off current <5nA at +85°C, enabling high-impedance sample-and-hold and sensor front-end applications.

| NO-Off Leakage | <2nA at +85°C - preserves accuracy 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 dynamic range without external level-shifting |
| Transition Time | <250ns - enables fast channel switching in automated test systems and real-time signal routing |
| Logic Compatibility | TTL/CMOS - simplifies interface with microcontrollers and FPGAs without pull-up resistors or translators |

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 max supply, 4.7Ω RON, but higher 12pC charge injection and no QSOP-16 option | Higher channel count and voltage rating; less suitable for low-leakage S&H where charge injection dominates error | Select ADG1418BRUZ only if 8-channel density or ±15V operation is required; verify charge injection impact on hold-step accuracy. |
| TS5A23157DGSR | Single-supply only (+1.65V to +5.5V), 0.9Ω RON, but rated only to +85°C and lacks dual-supply capability | Better RON for low-voltage audio, but incompatible with bipolar ±5V industrial signal chains | Choose TS5A23157DGSR for cost-sensitive, single-supply consumer audio; avoid in dual-supply or high-temp industrial designs. |
Compared with ADG1418BRUZ and TS5A23157DGSR, the MAX4518CEE+T uniquely balances low charge injection, dual-supply flexibility, and industrial temperature range - making it optimal for precision, mixed-signal embedded systems requiring both accuracy and ruggedness.

FAQ
What is the maximum operating temperature range for the MAX4518CEE+T?
The MAX4518CEE+T is specified for operation from -40°C to +85°C, meeting industrial temperature requirements. This rating is confirmed in the Ordering Information table, where "EEE" suffix denotes the -40°C to +85°C grade, and the device is packaged in a 16-pin QSOP. The datasheet guarantees leakage, on-resistance, and switching performance across this full range.
Does the MAX4518CEE+T support dual-supply operation, and what are the valid voltage ranges?
Yes, the MAX4518CEE+T supports dual-supply operation from ±2.7V to ±8V, with V+ and V− referenced to GND. The absolute maximum ratings allow V+ up to +17V and V− down to -17V, but functional operation requires |V+ − V−| ≤ 17V. For example, ±5V, ±3V, or asymmetric supplies like +10V/−5V are all valid per the Electrical Characteristics tables.
How many analog channels does the MAX4518CEE+T provide, and how is channel selection implemented?
The MAX4518CEE+T is a 4-channel analog multiplexer: it routes one of four normally-open inputs (NO1–NO4) to a common output (COM) using two address bits (A0, A1) and an active-high enable (EN). The truth table confirms that EN = high and A1/A0 = 00, 01, 10, or 11 selects NO1, NO2, NO3, or NO4 respectively - with all switches disabled when EN = low.
What is the typical on-resistance flatness specification for the MAX4518CEE+T, and why does it matter?
The MAX4518CEE+T guarantees on-resistance flatness of ≤10Ω over its full analog signal range (e.g., VCOM = ±4.5V). This means RON varies by no more than 10Ω as the signal swings - critical for maintaining linearity in precision gain stages, programmable gain amplifiers, and ratiometric sensor interfaces where resistance variation introduces harmonic distortion or gain error.
Is the MAX4518CEE+T pin-compatible with other variants in the MAX4518 family, such as the MAX4518CPD or MAX4518CSD?
No - the MAX4518CEE+T uses a 16-pin QSOP package, while MAX4518CPD (14-pin PDIP) and MAX4518CSD (14-pin SO) have different pin counts and layouts. The QSOP version adds two N.C. pins and relocates several terminals (e.g., COM moves from pin 13 in SO to pin 13 in QSOP, but NO2 shifts from pin 14 to pin 16). Always consult the specific pin configuration diagrams for each package variant.
