Product details
Overview
MAX4581LESE+T from Maxim Integrated is an 8-channel CMOS analog multiplexer configured for rail-to-rail signal switching in low-voltage systems. It operates with ±2V to ±6V dual supplies or +2V to +12V single supply, features 80Ω on-resistance at ±5V, 1nA off-leakage at +25°C, and TTL/CMOS-compatible logic inputs-enabling precise signal routing in battery-powered instrumentation and portable audio interfaces.
For engineers reviewing the MAX4581LESE+T datasheet, MAX4581LESE+T pinout, MAX4581LESE+T application, or MAX4581LESE+T equivalent, key selection criteria include guaranteed on-resistance matching across channels, low distortion (<0.02% at 600Ω), high off-isolation (–74dB at 50Ω), and AEC-Q100-qualified variants for automotive signal conditioning.
Technical Context
The MAX4581LESE+T implements a single 8:1 analog multiplexer architecture with three address inputs (A, B, C) and an active-low ENABLE terminal. Its CMOS switch core uses matched P- and N-channel transistors to achieve rail-to-rail analog conduction and break-before-make switching with <20ns transition time.
It supports dual-supply operation where VCC and VEE set analog signal swing limits, and internal ESD diodes clamp signals exceeding supply rails. Logic-level translators isolate digital control from analog paths, ensuring TTL/CMOS compatibility across supply voltages from +2V to +12V without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel single-pole multiplexer (8:1) |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables direct interfacing with Li-ion, 3.3V, and 5V systems |
| On-Resistance | 80Ω max at ±5V - ensures minimal gain error and voltage drop in precision sensor signal chains |
| Off-Leakage Current | 1nA at +25°C - preserves accuracy in high-impedance data-acquisition front-ends |
| Logic Thresholds | 0.8V to 2.4V - guarantees reliable switching with standard 5V TTL and CMOS drivers |
| Off-Isolation | –74dB at 50Ω, 1MHz - suppresses crosstalk between unused channels in multi-signal routing |
| Total Harmonic Distortion | <0.02% at 600Ω, 20Hz–20kHz - maintains fidelity in audio and measurement applications |
Pinout & Package
MAX4581LESE+T is housed in a 16-pin narrow SO (SOIC-16) package with exposed pad (RoHS-compliant, lead-free). Pin 1 is X0; pin 16 is VCC; pin 8 is GND; pin 7 is VEE; pin 9 is ENABLE (active-low); pins 10–12 are address inputs A, B, C; pins 13–15 and 1–6 are analog I/O terminals X0–X7 and X (common output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| X0–X7 | Analog input channels 0–7 | Bidirectional, rail-to-rail capable; interchangeable as input or output |
| X | Common analog output | Single-pole connection point for all 8 channels; no internal buffering |
| A, B, C | Digital address inputs | Binary-select lines determining active channel (CBA = 000 → X0, 111 → X7) |
| ENABLE | Active-low enable control | Pulls all switches open when high; required for power-down mode |
| VCC | Positive supply | Drives internal logic and P-channel switches; sets upper analog rail limit |
| VEE | Negative supply | Drives N-channel switches; sets lower analog rail limit; tie to GND for single-supply use |
| GND | Digital ground reference | Logic return path only; no analog signal reference - analog signals float between VCC and VEE |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from VEE to VCC without clipping or distortion |
| Guaranteed on-resistance match | ΔRON ≤ 10Ω across channels - critical for gain-matched multi-channel ADC front-ends |
| Low charge injection | 0.5–5pC - minimizes voltage glitch on high-impedance nodes during switching |
| High off-isolation | –74dB at 1MHz - prevents signal bleed-through in sensitive RF or sensor multiplexing |
| TTL/CMOS logic compatibility | Valid thresholds at 0.8V/2.4V with ±5V or +5V supply - eliminates external level shifters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4581CSE+ | Same 8:1 mux function, but rated for 0°C to +70°C industrial range (vs. –40°C to +85°C for MAX4581LESE+T) | Not qualified for extended temperature or automotive use; suitable for commercial-grade embedded systems | Select when ambient operating temperature remains within 0°C–70°C and AEC-Q100 compliance is unnecessary |
| ADG1408BRUZ | 8:1 mux with 4.7Ω typical on-resistance (lower than MAX4581LESE+T's 80Ω), but requires ≥±4.5V dual supply or ≥9V single supply | Higher performance in low-RON applications (e.g., precision current sensing), but incompatible with sub-5V battery systems | Select when ultra-low on-resistance is critical and system can support higher supply voltages |
Compared with MAX4581CSE+, MAX4581LESE+T offers wider temperature coverage and automotive qualification; compared with ADG1408BRUZ, it trades lower on-resistance for broader supply flexibility down to +2V, making it optimal for portable and low-power designs.

FAQ
What is the maximum analog signal range supported by MAX4581LESE+T?
The MAX4581LESE+T supports rail-to-rail analog signals from VEE to VCC. With ±5V supplies, this equals –5V to +5V; with +5V single supply (VEE = GND), it supports 0V to +5V. The device tolerates signals up to (VEE – 0.3V) and (VCC + 0.3V) due to internal ESD clamps, but sustained operation beyond VEE/VCC risks increased leakage.
Does MAX4581LESE+T require external level-shifting for 3.3V microcontroller control?
No. MAX4581LESE+T logic inputs accept 0.8V to 2.4V thresholds, fully compatible with 3.3V CMOS outputs (which typically drive >2.4V high and <0.4V low). No level shifter is needed when interfacing with standard 3.3V MCUs, even with ±5V analog supplies.
Can MAX4581LESE+T be used in a single-supply configuration with VEE tied to GND?
Yes. MAX4581LESE+T operates with VEE = GND and VCC = +2V to +12V. In this mode, analog signals swing from 0V to VCC. On-resistance increases to 150Ω at +5V (vs. 80Ω at ±5V), and off-isolation degrades slightly-but all specifications remain guaranteed per datasheet.
What is the break-before-make interval for MAX4581LESE+T, and why does it matter?
The MAX4581LESE+T guarantees a break-before-make time of 4–20ns (typ. 10ns) at +25°C. This prevents momentary shorting between channels during address transitions-critical in applications like sensor multiplexing where simultaneous connection could cause measurement errors or damage to upstream sources.
How does charge injection affect precision applications using MAX4581LESE+T?
MAX4581LESE+T exhibits 0.5–5pC charge injection (typ. 2pC), which induces a voltage glitch ΔV = Q/CL on downstream capacitive nodes. For a 100pF sample capacitor, this yields ≤50mV glitch-manageable via hold-time extension or buffer isolation. It is guaranteed by design and validated in production test.
