Product details
Overview
MAX4051AEEE+ 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 sensor signal routing.
For engineers reviewing the MAX4051AEEE+ datasheet, MAX4051AEEE+ pinout, MAX4051AEEE+ application, or MAX4051AEEE+ equivalent, key selection criteria include guaranteed on-resistance match (≤6Ω), low charge injection (≤10pC), high off-isolation (<–90dB), and QSOP-16 package compatibility with space-constrained portable instrumentation designs.
Technical Context
The MAX4051AEEE+ implements a single 8:1 analog multiplexer using complementary MOSFET switch pairs per channel, driven by decoded ADDA/ADDB/ADDC address inputs and controlled by an active-low INH inhibit. Its internal logic-level translators isolate digital control signals from analog supply rails (V+, V−), enabling robust operation across wide supply ranges without level-shifting circuitry.
All NO/COM terminals are bidirectional and functionally identical; switching is break-before-make with ≤225ns turn-on and ≤275ns turn-off times under ±5V dual-supply conditions. On-resistance flatness is guaranteed at ≤10Ω over the full analog signal range, ensuring minimal gain error in precision measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (1-of-8 selector) |
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures <0.1% gain error in 10kΩ source/load impedance applications |
| On-resistance match (∆RON) | 6Ω max - enables precise ratiometric measurements across channels |
| Off-leakage current | 0.1nA max at +25°C - preserves accuracy in high-impedance sensor front-ends (e.g., pH electrodes) |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports battery-powered and industrial rail-flexible designs |
| Logic thresholds | 0.8V to 2.4V - guarantees reliable TTL/CMOS interfacing without external level shifters |
| Off-isolation | <–90dB at 100kHz - suppresses crosstalk between inactive channels in multi-signal systems |
Pinout & Package
MAX4051AEEE+ is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch and 5.0mm × 3.99mm body size, optimized for automated assembly and thermal performance in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal switch gates and logic; sets upper analog signal limit (rail-to-rail up to V+) |
| V− | Negative analog supply | Drives internal switch gates; sets lower analog signal limit (rail-to-rail down to V−); tied to GND for single-supply use |
| GND | Digital ground reference | Reference for logic inputs only; no analog signal return path - analog signals float between V+ and V− |
| INH | Digital inhibit input | Active-high; forces all switches open when asserted - enables system-level power gating |
| ADDA, ADDB, ADDC | 3-bit binary address inputs | Select one of eight NOx inputs to connect to COM; ADDC not used on MAX4052 variants |
| COM | Common analog terminal | Bidirectional I/O; connects to selected NOx channel - serves as multiplexer output or input depending on signal flow |
| NO0–NO7 | Eight normally-open analog inputs | Bidirectional; pass analog signals equally in either direction; interchangeable with COM in layout |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy HC4051 designs without PCB revision |
| Guaranteed on-resistance match | ≤6Ω channel-to-channel variation - critical for calibrated multi-channel ADC front-ends |
| Low charge injection | ≤10pC - minimizes voltage glitch on high-impedance nodes during switching |
| Rail-to-rail analog operation | Signals swing from V− to V+ - eliminates level-shifting in ±5V or +3.3V systems |
| Break-before-make switching | ≤225ns minimum break interval - prevents momentary shorting between channels |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051CEE+ | Standard-grade version with 12Ω max on-resistance match and 1nA max off-leakage at +25°C | Suitable for cost-sensitive industrial controls where tighter matching is not required | Select MAX4051CEE+ when budget constraints outweigh need for sub-1nA leakage or ≤6Ω RON match |
| ADG1408BRUZ | 8-channel mux with 4.7Ω on-resistance, 1pA off-leakage, but requires ≥±4.5V dual or ≥9V single supply | Better leakage and RON specs, but incompatible with +3.3V-only or ±3V systems | Choose ADG1408BRUZ only if supply rails permit ≥±4.5V and ultra-low leakage justifies higher cost |
Compared with MAX4051CEE+, the MAX4051AEEE+ delivers tighter on-resistance matching and lower leakage for precision measurement, while ADG1408BRUZ offers superior leakage performance at the expense of supply flexibility and pin compatibility.

FAQ
What is the maximum analog signal range supported by the MAX4051AEEE+?
The MAX4051AEEE+ supports rail-to-rail analog signals from V− to V+, meaning it passes voltages spanning the full range between its negative and positive supply rails. With ±5V supplies, this is –5V to +5V; with +5V single supply (V− = GND), it handles 0V to +5V. This eliminates the need for external level-shifting circuitry in most applications.
Does the MAX4051AEEE+ require external pull-up or pull-down resistors on its address pins?
No, the MAX4051AEEE+ does not require external pull-up or pull-down resistors on ADDA, ADDB, or ADDC pins. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (0.8V to 2.4V) and low input current (±1µA), allowing direct connection to microcontroller GPIOs or logic buffers without additional biasing components.
Can the MAX4051AEEE+ operate from a +3.3V single supply?
Yes, the MAX4051AEEE+ operates from a +3.3V single supply (V+ = +3.3V, V− = GND). At this voltage, typical on-resistance increases to ~525Ω, and switching times lengthen (e.g., tON ≈ 600ns), but all functionality-including logic compatibility and leakage specs-remains fully specified and guaranteed per the datasheet.
How does the INH pin function on the MAX4051AEEE+?
The INH (Inhibit) pin on the MAX4051AEEE+ is an active-high digital input that forces all internal switches into the open (off) state when driven high, regardless of address inputs. When pulled low or grounded, normal multiplexer operation resumes. This enables system-level power gating or fault-safe shutdown without changing address lines.
Is the MAX4051AEEE+ pin-compatible with the industry-standard 74HC4051?
Yes, the MAX4051AEEE+ is pin-compatible with the 74HC4051 in the same 16-pin package. It shares identical pin assignments for V+, V−, GND, INH, ADDA–ADDC, COM, and NO0–NO7. This allows direct replacement in existing HC4051-based designs while delivering improved on-resistance matching, lower leakage, and wider supply range support.
