Product details
Overview
MAX4611ESD from Maxim Integrated is a quad, low-voltage, single-pole/single-throw (SPST) CMOS analog switch with four normally closed (NC) channels. It operates from a single +2V to +12V supply, delivers ≤100Ω on-resistance at +5V, matches on-resistance between channels to ≤4Ω, and supports rail-to-rail analog signal handling (GND to V+). It is used in battery-powered audio routing and low-voltage data-acquisition systems where leakage-critical switching is required.
For engineers reviewing the MAX4611ESD datasheet, MAX4611ESD pinout, MAX4611ESD application, or MAX4611ESD equivalent, key selection criteria include guaranteed on-resistance flatness (≤18Ω), sub-2nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and 14-pin narrow SO package suitability for space-constrained industrial signal-path designs.
Technical Context
The MAX4611ESD implements four independent NC analog switches using matched CMOS transmission-gate topology. Each channel features bidirectional rail-to-rail conduction, internal ESD protection (>2kV per Method 3015.7), and logic inputs with fixed +0.8V/+2.4V thresholds at +5V supply - ensuring direct interface with standard TTL/CMOS drivers without level shifting.
Its analog performance is characterized by low charge injection (1–5pC), high off-isolation (−60dB at 1MHz), and wide bandwidth (300MHz on-channel), making it suitable for precision sampling and high-fidelity audio switching where signal integrity and crosstalk suppression are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V single supply - enables direct integration into 3.3V, 5V, and 9V battery or industrial rails without auxiliary regulators. |
| On-Resistance (RON) | ≤100Ω max at +5V - ensures minimal voltage drop and power loss in low-level sensor or audio signal paths. |
| On-Resistance Match (ΔRON) | ≤4Ω max between channels - guarantees consistent gain/attenuation across multiplexed channels in instrumentation front-ends. |
| Off-Leakage Current | ≤2nA at TA = +85°C - preserves accuracy in high-impedance sample-and-hold or sensor-bias networks. |
| Analog Signal Range | GND to V+ - supports full-rail signal routing without clipping in unipolar data-acquisition systems. |
| Logic Compatibility | +0.8V low / +2.4V high thresholds at +5V - interoperates directly with 5V TTL and CMOS microcontrollers and FPGAs. |
| ESD Protection | >2kV per Method 3015.7 - reduces need for external transient suppression in handheld or field-deployable equipment. |
Pinout & Package
MAX4611ESD is supplied in a 14-pin narrow SO (small outline) package with exposed pad not present - distinct from QFN variants. Pin 7 is GND; pins 1, 3, 8, 11 are NC terminals; pins 2, 4, 9, 10 are COM1–COM4; pins 13, 5, 6, 12 are IN1–IN4; pin 14 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NC1–NC4 (Normally Closed) | Analog output terminals that conduct to COMx when corresponding INx is LOW; open when INx is HIGH. |
| 2, 4, 9, 10 | COM1–COM4 (Common) | Shared analog signal path nodes - each connects bidirectionally to its paired NCx terminal when enabled. |
| 13, 5, 6, 12 | IN1–IN4 (Digital Control) | TTL/CMOS-compatible inputs - LOW activates NC path; HIGH disables conduction (open circuit). |
| 7 | GND | Digital and analog reference ground - must be low-impedance connection to minimize noise coupling. |
| 14 | V+ | Single positive supply for analog and digital circuitry - powers internal biasing and defines signal range (GND to V+). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without distortion or clipping - eliminates need for level-shifting in unipolar systems. |
| Guaranteed on-resistance flatness | ≤18Ω variation over full signal range - maintains linear gain response in precision amplifier or filter switching applications. |
| Matched channel on-resistance | ≤4Ω max mismatch - enables accurate differential or ratiometric measurements across switched sensor inputs. |
| Low off-leakage current | ≤2nA at +85°C - prevents DC error accumulation in high-Z sample-and-hold capacitors or pH/electrochemical sensor interfaces. |
| High off-isolation | −60dB at 1MHz - suppresses crosstalk between adjacent audio or RF signal paths in multi-channel routing. |
Applications
| Battery-Powered Audio Routing | Low-Voltage Data-Acquisition Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4611EUD+ | Same electrical specs and pinout; differs only in TSSOP-14 package (vs. SO-14 for MAX4611ESD). | Preferred for automated SMT assembly with finer pitch; requires different land pattern and stencil design. | Select MAX4611EUD+ when board layout supports TSSOP footprint and higher-density placement is needed. |
| ADG1411BRZ | Quad SPST NC switch with 1.8Ω typical RON (vs. 100Ω max for MAX4611ESD); requires dual ±5V or single +15V supply. | Better suited for low-RON, high-precision instrumentation; incompatible with +3.3V-only systems due to supply requirements. | Choose ADG1411BRZ only if <2Ω RON and sub-pA leakage are mandatory, and supply architecture supports ±5V or +15V rails. |
Compared with MAX4611EUD+, MAX4611ESD offers identical switching performance in a mature, widely qualified SOIC package with proven thermal reliability in industrial temperature range (−40°C to +85°C); versus ADG1411BRZ, MAX4611ESD provides superior supply flexibility (+2V to +12V) and lower system cost but trades off ultra-low on-resistance for broader voltage compatibility.

FAQ
What is the maximum supply voltage rating for MAX4611ESD?
The absolute maximum supply voltage (V+) for MAX4611ESD is +13V referenced to GND. Operation above this level risks permanent damage. For reliable +12V operation, a minimum 0.1µF bypass capacitor must be placed close to the V+ pin. The device is fully specified from +2V to +12V, with on-resistance dropping to ≤46Ω at +12V supply.
Does MAX4611ESD support rail-to-rail analog signal switching?
Yes, MAX4611ESD supports true rail-to-rail analog signal handling: the analog signal range extends from GND to V+ for all COM, NC, and NO terminals. This allows unclipped switching of full-scale signals in single-supply systems such as battery-powered sensors or audio interfaces without external level-shifting circuitry.
What is the logic threshold behavior of MAX4611ESD at +3.3V supply?
MAX4611ESD is not characterized for +3.3V logic thresholds - its guaranteed input thresholds (+0.8V low, +2.4V high) apply only at +5V supply. At +3.3V, VIN_H and VIN_L shift downward per datasheet tables; for robust 3.3V logic compatibility, external level translation or verification against actual operating margins is recommended.
How does the on-resistance of MAX4611ESD vary with temperature and signal voltage?
MAX4611ESD's on-resistance increases with temperature and varies across the analog signal range. At +25°C and +5V supply, RON is ≤100Ω and exhibits ≤18Ω flatness (max difference between min/max RON over 0V to +5V). Over −40°C to +85°C, RON rises - e.g., at +85°C and +5V, typical RON is ~120Ω with same flatness guarantee.
Is MAX4611ESD pin-compatible with industry-standard analog switches?
Yes, MAX4611ESD is pin-compatible with the industry-standard 74HC4066 and Maxim's own MAX4066 in the 14-pin narrow SO package. This allows drop-in replacement in existing designs targeting low-voltage operation, though designers must verify logic thresholds and leakage performance meet updated system requirements.
