Product details
Overview
MAX4051AEEE+T from Maxim Integrated is an 8-channel CMOS analog multiplexer with rail-to-rail signal handling, ±2.7V to ±8V dual-supply or +2.7V to +16V single-supply operation, 100Ω typical on-resistance at ±5V, 0.1nA max off-leakage at +25°C, and TTL/CMOS logic compatibility - used in low-voltage data-acquisition systems for precision signal routing.
For engineers reviewing the MAX4051AEEE+T datasheet, MAX4051AEEE+T pinout, MAX4051AEEE+T application, or MAX4051AEEE+T equivalent, key selection criteria include guaranteed on-resistance match (≤6Ω), low charge injection (≤10pC), high off-isolation (<–90dB), and QSOP-16 packaging for space-constrained mixed-signal PCBs.
Technical Context
The MAX4051AEEE+T implements a single 8:1 analog multiplexer using CMOS transmission-gate architecture with independent digital address decoding (ADDA, ADDB, ADDC) and global inhibit (INH). Its internal logic-level translators isolate digital control signals from analog supply rails (V+, V−), enabling robust operation across wide voltage ranges without level-shifting circuitry.
All NO/COM terminals are bidirectional and functionally identical; switching is break-before-make with 30ns typical tOPEN at +25°C. The device guarantees matched on-resistance flatness (≤10Ω) and low distortion (<0.04% at 600Ω), making it suitable for audio-grade and precision instrumentation signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (1-of-8 selector) |
| Supply Range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - supports battery-powered and industrial rail-flexible designs |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in sensor front-ends |
| On-Resistance Match | 6Ω max between channels - critical for ratiometric measurements and channel calibration |
| Off-Leakage Current | 0.1nA max at +25°C - preserves accuracy in high-impedance pH, thermocouple, or photodiode interfaces |
| Off-Isolation | <–90dB at 100kHz (50Ω) - prevents crosstalk between unused channels in multi-sensor systems |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V supply - ensures reliable TTL/CMOS interfacing without external level shifters |
Pinout & Package
MAX4051AEEE+T is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch and 3.9mm × 4.9mm body size - optimized for automated assembly and thermal performance in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 (Normally Open) | Bidirectional analog inputs; interchangeable with COM; support rail-to-rail signal routing |
| 3 | COM (Common) | Single bidirectional analog output/input; connects to selected NOx channel when enabled |
| 6 | INH (Inhibit) | Active-high global disable; forces all switches open regardless of address state |
| 7 | V− | Negative analog supply; tied to GND for single-supply operation |
| 8 | GND | Digital ground reference only; no analog return path - isolates digital noise from analog paths |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs selecting one of eight NO channels (000–111) |
| 16 | V+ | Positive analog/digital supply; powers internal logic translators and switch gates |
Key Features

IC Role / Device Role / Timing Role: Precision analog switch with guaranteed timing specs (tON/tOFF ≤200ns) for synchronized test sequencing. Use Value: Break-before-make delay (30ns) prevents shorting of test resources; 100Ω RON ensures predictable load matching during calibration routines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | Higher on-resistance (1.8Ω typical), wider supply range (±15V), but higher leakage (2nA) and larger TSSOP-16 package | Better suited for high-voltage industrial actuator control; less optimal for ultra-low-leakage sensor front-ends | Select ADG1408BRUZ when ±15V operation or lower RON tempco is required; avoid where sub-1nA leakage is mandatory |
| TMUX1308PWR | Lower supply range (+1.08V to +3.6V), smaller X2QFN-16 package, but higher RON (120Ω) and no dual-supply support | Targeted for ultra-low-power wearables; lacks bipolar capability for legacy industrial designs | Choose TMUX1308PWR for battery-critical IoT edge nodes; not viable for ±5V or rail-to-rail analog systems |
Compared with ADG1408BRUZ and TMUX1308PWR, MAX4051AEEE+T uniquely balances low leakage (0.1nA), dual-supply flexibility (±2.7V to ±8V), and industry-standard QSOP-16 packaging - making it the preferred choice for mixed-signal industrial and medical equipment requiring proven reliability and broad voltage compatibility.

FAQ
What is the maximum operating temperature range for the MAX4051AEEE+T?
The MAX4051AEEE+T is rated for operation from –40°C to +85°C, as confirmed by its "E" grade temperature specification and QSOP packaging qualification. This extended range supports deployment in industrial control cabinets and automotive under-hood environments where ambient temperatures exceed commercial-grade limits. The MAX4051AEEE+T maintains guaranteed on-resistance match and leakage performance across this full span.
Does the MAX4051AEEE+T support single-supply operation below +3V?
The MAX4051AEEE+T is specified down to +2.7V for single-supply operation per its Absolute Maximum Ratings and Electrical Characteristics tables. While functional behavior may occur near +1.7V, Maxim does not guarantee parameters such as on-resistance, leakage, or switching time below +2.7V. For reliable operation in low-voltage battery systems, design to the +2.7V minimum - and verify RON (up to 700Ω at +3V) and tON (up to 600ns) under actual conditions.
How does the INH pin function on the MAX4051AEEE+T?
The INH (Inhibit) pin on the MAX4051AEEE+T is an active-high digital input that globally disables all internal switches when driven logic high, forcing the COM terminal to disconnect from all NO0–NO7 channels regardless of ADDA/ADDB/ADDC states. When INH is low or grounded, normal address-controlled switching resumes. This feature enables fast system-level channel blanking during fault conditions or calibration sequences in the MAX4051AEEE+T.
Can the NO and COM pins of the MAX4051AEEE+T be used interchangeably?
Yes - the NO and COM pins of the MAX4051AEEE+T are fully bidirectional and electrically identical per Maxim's Pin Descriptions and Applications Information sections. Signals pass with equal performance in either direction, and any NO pin can serve as the common node while COM functions as a channel input. This symmetry simplifies PCB layout and enables flexible signal routing topologies in the MAX4051AEEE+T without performance penalty.
What is the guaranteed on-resistance flatness for the MAX4051AEEE+T?
The MAX4051AEEE+T guarantees on-resistance flatness of ≤10Ω over its full analog signal range (VCOM = ±3V with ±5V supplies), defined as the difference between maximum and minimum RON measured across the signal swing. This tight flatness ensures consistent gain and minimal harmonic distortion (<0.04% at 600Ω) in audio and instrumentation applications - a key differentiator from non-A-suffix variants which lack this characterization.
